The need for a compact, economical, and low-power wireless system has given birth to the
System-on-Chip (SoC) concept viable of a multitude of innovative applications. On-Chip …

This paper proposes a surface-acoustic wave (SAW)-less tunable RF front end (RF-FE)
using an electrical-balance duplexer (EBD) integrated with a switched-LC N-path low-noise …

Full-duplex (FD) wireless-simultaneous transmission and reception on the same frequency-
is a promising technique that can significantly improve spectrum efficiency and reduce …

Practical, in-band, full-duplex (IBFD) systems typically require more than 100 dB of self-
interference cancellation (SIC). Digital processing alone is insufficient for achieving this …

Two Kuto V-band distributed amplifiers (DAs) based on nMOS and nMOS/pMOS gain stages
and a distributed transceiver front end (DTFE) are presented for ultra-wideband power and …

This article presents a quadrature balanced radio-frequency (RF) front-end transmitter (TX)
architecture assisted by a digital self-interference cancellation (SIC) algorithm for …

An electrical balance duplexer (EBD) supports dual-band TX-RX isolation enabling
frequency-division duplexing (FDD) operation at 5-7 GHz for Wi-Fi 6/6E. A programmable …

Antenna-coupling group delay limits the cancellation bandwidth of conventional self-
interference cancellers (SICs), making it difficult to ensure isolation in both transmit (TX) and …

Circulators and quasi-circulators (QCs) have a tradeoff between maximum isolation and
bandwidth. We present a tunable distributed active circuit to achieve high isolation over a …

A highly linear receiver (RX) front end with integrated hybrid transformer (HT) for frequency-
division duplexing mobile communications is reported. The HT, implemented with a three …
