This article presents the principles of operation of a reflection-mode $N$ -path filter and then discusses both single-balanced and double-balanced implementations. The single-balanced approach can be used to realize tunable filters with extremely lo

This article presents architectures to realize mutual impedance tuning for N -path mixer-first multiple-input multiple-output (MIMO) receivers. A coupled response at baseband is upconverted to radio frequency to realize the tunable mutual impedance.

In this paper, we analyze a mixer-first receiver, which includes passive polyphase mixers, low-noise baseband amplifiers, and baseband circulant-symmetric polyphase feedback. This analysis is performed for input frequencies located around any harmoni

N-phase mixer-first receivers are an ideal choice for broadband frequency-selective receivers. These receivers can now operate near millimeter-wave frequencies using fast-rising four-phase clock generation in advanced CMOS. This paper compares four-p

This paper introduces mutual impedance tuning for N-path mixer-first MIMO receivers, useful for dynamic decoupling of coupled-antenna systems. A two-port mixer-first MIMO receiver is realized in 45-nm SOI CMOS and includes polyphase baseband resistiv

A 20–30 GHz mixer-first receiver implemented in 45-nm SOI CMOS is presented. The receiver employs four-phase passive mixing with input inductor to realize tunable impedance matching up to 30 GHz. The receiver achieves an 8-dB noise figure with reco
