The N-path filter concept, also known as commutated filter or frequency translated filter, can
offer high-Q and high-linearity RF-filtering with acceptable noise. This chapter reviews …

A new wideband receiver architecture is proposed that employs two separate passive-mixer-
based downconversion paths, which enables noise cancelling, but avoids voltage gain at …

A design methodology for synthesis of active N-path bandpass filters is introduced. Based
on this methodology, a 0.1-to-1.2 GHz tunable 6th-order N-path channel-select filter in 65 …

A wideband RF receiver employs a multi-loop architecture to ease the tradeoff between
noise and linearity, a new method of harmonic rejection that relaxes gain and phase …

A widely tunable 4th order BPF based on the subtraction of two 2nd order 4-path passive-
mixer filters with slightly different center frequencies is proposed. The center frequency of …

N-path switched-RC circuits can realize filters with very high linearity and compression point
while they are tunable by a clock frequency. In this paper, both differential and single-ended …

Channel selection at the input of RF receivers can considerably relax linearity requirements,
leading to low-power, compact implementations. A GSM/WCDMA/802.11 b/g receiver …

A low-power interferer-robust mixer-first receiver front end that uses a novel capacitive
stacking technique in a bottom-plate N-path filter/mixer is proposed. Capacitive stacking is …

This article presents a comprehensive survey of the literature on self-interference (SI) in long-
term evolution advanced (LTE-A) and fifth-generation (5G) new radio transceivers and …

An RF front end with a harmonic-rejecting N-path filter is presented. It features tunable
narrow-band filtering and high attenuation at the third-and fifth-order local oscillator (LO) …
