A Fully Passive RF Front End With 13-dB Gain Exploiting Implicit Capacitive Stacking in a Bottom-Plate N-Path Filter/Mixer
TL;DR: A step-up transformer is used to improve the out-of-band (OOB) linearity performance of small switches in the N-path mixer, thereby reducing the power consumption of switch drivers.
Journal ArticleDOI
Design and Analysis of a DCO-Based Phase-Tracking RF Receiver for IoT Applications
TL;DR: The proposed RX, with the DCO acting as a local oscillator (LO) and binary frequency feedback, promotes low-power and low-voltage circuit design, while a data-aided carrier-frequency tracking ensures the received carrier stability without a power-/area-hungry phase-locked loop (PLL).
Journal ArticleDOI
Low-Power High-Linearity Mixer-First Receiver Using Implicit Capacitive Stacking With 3x Voltage Gain
TL;DR: A passive mixer-first receiver front end providing a low-power integrated solution for high interference robustness in radios targeting Internet-of-Things (IoT) applications and using at least 2 $\times $ less total capacitance for the same RF bandwidth compared to a conventional switch-capacitor N-path filter.
Proceedings ArticleDOI
A Sub-mW All-Passive RF Front End with Implicit Capacitive Stacking Achieving 13 dB Gain, 5 dB NF and +25 dBm OOB-IIP3
TL;DR: In this paper, a sub-mW mixer-first RF front-end that exploits a novel capacitive stacking technique in an altered bottom-plate N-path filter/mixer to achieve passive voltage gain and high-linearity at low noise figure is presented.
Journal ArticleDOI
