Design Of Analog Cmos Integrated Circuits

Reactive matching is extended to wide bandwidths using the impedance property of LC-ladder filters. In this paper, we present a systematic method to design wideband low-noise amplifiers. An SiGe amplifier with on-chip matching network spanning 3-10 GHz delivers 21-dB peak gain, 2.5-dB noise figure, and -1-dBm input IP3 at 5 GHz, with a 10-mA bias current.

This expanded and thoroughly revised edition of Thomas H. Lee's acclaimed guide to the design of gigahertz RF integrated circuits features a completely new chapter on the principles of wireless systems. The chapters on low-noise amplifiers, oscillators and phase noise have been significantly expanded as well. The chapter on architectures now contains several examples of complete chip designs that bring together all the various theoretical and practical elements involved in producing a prototype chip.

The Design of CMOS Radio-Frequency Integrated Circuits: RF CIRCUITS THROUGH THE AGES

As the reliability is a critical issue for new generation multi-level cell (MLC) flash memories, there is growing call for fast and compact error correction code (ECC) circuit with minimum impact on memory access time and chip area. This paper presents a high-throughput and low-power ECC scheme for MLC NAND flash memories. The BCH encoder and decoder architecture features byte-wise processing and a low complexity key equation solver using a simplified Berlekamp-Massey algorithm. Resource sharing and power reduction techniques are also applied. Synthesized using 0.25-mum CMOS technology in a supply voltage of 2.5 V, the proposed BCH (4148,4096) encoder/decoder achieves byte-wise processing, and it needs an estimated cell area of 0.2 mm2, and an average power of 3.18 mW with 50 MB/s throughput

Low-Power High-Throughput BCH Error Correction VLSI Design for Multi-Level Cell NAND Flash Memories

Test circuits for the signal detection and the function electrical stimulation (FES) of neurons have been designed, implemented at first by using discrete devices and characterized off-body. The detecting circuit consisting of three-stage operational amplifiers has a controllable gain up to 10/sup 5/, a -3 dB bandwidth of 30 kHz, and an equivalent input noise of about 9 nV//spl radic/Hz. The FES circuit consisting of two-stage operational amplifiers has a bandwidth of more than 10 kHz and a variable gain from 20 dB to 60 dB can provide a current of more than 1 mA to a load of 10 k/spl Omega/ They are intended to connect with both cuff-type and staff-type microelectrodes. Integrated circuits (IC) for the neural signal process have been designed with features of low voltage and low power. A more biocompatible composite has been synthesized to modify the silicon and related material.

Study of microelectronics for detecting and stimulating of central neural signals

A new design method for parallel BCH encoder is presented, which can eliminate the bottleneck in long BCH encoder. Based on serial LFSR architecture, a recursive formula which can deduce the parallel BCH encoder was first derived. The complexity and the delay of the critical paths of the circuit could be effectively decreased by using a tree-type structure, sharing sub-expression and limiting its maximum number, and balancing load technique. Finally, a parallel BCH (2184, 2040) encoder with 8-bit parallelism is realized in TSMC's 0.18 /spl mu/m CMOS technology for high-speed optical communication that can operate at 400 MHz and process data at the rate of 2.5 Gb/s.

Optimized design for high-speed parallel BCH encoder

We present a new technique to achieve uniform lateral electric field and maximum breakdown voltage in lateral double-diffused metal-oxide-semiconductor transistors fabricated on silicon-on-insulator substrates. A linearly increasing drift-region thickness from the source to the drain is employed to improve the electric field distribution in the devices. Compared to the lateral linear doping technique and the reduced surface field technique, two-dimensional numerical simulations show that the new device exhibits reduced specific on-resistance, maximum off- and on-state breakdown voltages, superior quasi-saturation characteristics and improved safe operating area.

This paper describes a large tuning range low phase noise voltage-controlled ring oscillator (ring VCO) based on a different cascade voltage logic delay cell with current-source load to change the current of output node. The method for optimization is presented. Furthermore, the analysis of performance of the proposed ring VCO is confirmed by the measurement results. The three-stage proposed ring VCO was fabricated in the 180-nm CMOS process of SMIC. The measurement results show that the oscillator frequency of the ring VCO is from 0.770 to 5.286 GHz and the phase noise is 97.93 dBc/Hz at an offset of 1 MHz from 5.268 GHz with a total power of 15.1 mW from a 1.8 V supply while occupying only 0.00175 mm2 of the core die area.

A 2.4GHz low phase noise CMOS LC voltage-controlled oscillator (VCO) is presented. By using a novel three-bit binary-weighted switched capacitor array, the VCO achieves a tuning range of 51.7% from 1.70GHz to 2.94GHz. Designed in SMIC 0.18-μm CMOS technology, the proposed VCO occupies a size of 500μm×700μm. The VCO achieves a phase noise of −123.8dBc/Hz at 1MHz offset from the carrier frequency of 2.4GHz and draws 8.4mA current from 1.8V supply.
