Proceedings ArticleDOI
A 54mW 1.2GS/s 71.5dB SNDR 50MHz BW VCO-based CT ΔΣ ADC using dual phase/frequency feedback in 65nm CMOS
TL;DR: A wide bandwidth VCO-based continuous-time ΔΣ modulator that uses combined phase and frequency feedback to mitigate VCO non-linearity and ease DEM timing requirement is presented.
Journal ArticleDOI
A 50 MHz BW 76.1 dB DR Two-Stage Continuous-Time Delta–Sigma Modulator With VCO Quantizer Nonlinearity Cancellation
TL;DR: The presented modulator suppresses the VCOQ voltage-to-frequency nonlinearity through dual path cancellation to achieve high linearity and exhibits strong immunity to the first stage quantization error leakage to the output due to gain mismatches between the two stages.
Journal ArticleDOI
A 0.49–13.3 MHz Tunable Fourth-Order LPF with Complex Poles Achieving 28.7 dBm OIP3
Pedram Payandehnia,Hamidreza Maghami,Hossein Mirzaie,Manjunath Kareppagoudr,Siladitya Dey,Massoud Tohidian,Gabor C. Temes +6 more
TL;DR: A novel switched-capacitor low-pass filter architecture is presented, in which a feedback path is added to a charge-rotating real-pole filter to implement complex poles and the selectivity is enhanced, and the in-band loss is reduced compared with the real- pole filter.
Journal ArticleDOI
A Highly Linear OTA-Less 1-1 MASH VCO-Based $\Delta\Sigma$ ADC With an Efficient Phase Quantization Noise Extraction Technique
Hamidreza Maghami,Pedram Payandehnia,Hossein Mirzaie,Ramin Zanbaghi,Hossein Zareie,Justin B. Goins,Siladitya Dey,Kartikeya Mayaram,Terri S. Fiez +8 more
TL;DR: An efficient technique is introduced to extract the quantization noise of a multi-phase voltage-controlled oscillator (VCO)-based quantizer (V COQ) in the time domain as a pulsewidth modulated (PWM) signal.
Journal ArticleDOI
350 mV, 5 GHz Class-D Enhanced Swing Differential and Quadrature VCOs in 65 nm CMOS
TL;DR: A new enhanced swing class-D VCO which operates from a supply voltage as low as 300 mV is presented, and the architectural advantages are described along with an analysis for the oscillation frequency.
