Author(s): Erwin Hardeveld, Ronan van der Zee, Bram Nauta

Abstract:

In this article, we propose a wideband mixer-first receiver with improved in-band (IB) linearity. It uses bootstrapped N-path mixer switches to achieve a constant on-state gate–source voltage for large IB signals. We analyze the tradeoff between on-state resistance and off-state subthreshold current in conventional mixer switches and introduce a …

A Capacitive Stacking Mixer-First Receiver With Higher Order Capacitive Feedback

A Capacitive Stacking Mixer-First Receiver With Higher Order Capacitive Feedback 150 150
Author(s): Stef van Zanten, Ronan A. R. van der Zee, Bram Nauta

Abstract:

This article presents a capacitive stacking mixer-first receiver (MF-RX) with a higher order capacitive feedback (CFB) loop designed to increase interferer rejection right at the mixer baseband (BB) node, benefiting both the out-of-band (OOB) linearity of the passive mixer switches and the active BB circuitry. The CFB loop consists of …
