Abstract: A receiver includes circuitry configured to determine one or more first local oscillator (LO) harmonics that correspond to one or more first spectrum segments of a down-converted received signal based on characteristics of the received signal. The one or more first LO harmonics of the received signal are amplified by applying one or more first transconductance coefficients to one or more first harmonic selective transinductance amplifiers (TIAs) corresponding to the one or more first spectrum segments. Digitized outputs of the plurality of harmonic selective TIAs are calibrated based on an amount of signal leakage between the plurality of spectrum segments of the down-converted received signal.

Abstract: A circuit for a single differential-inductor oscillator with common-mode resonance may include a tank circuit formed by coupling a first inductor with a pair of first capacitors; a cross-coupled transistor pair coupled to the tank circuit; and one or more second capacitors coupled to the tank circuit and the cross-coupled transistors. The single differential-inductor oscillator may be configured such that a common mode (CM) resonance frequency (FCM) associated with the single differential-inductor oscillator is at twice a differential resonance frequency (FD) associated with the single differential-inductor oscillator.

Abstract: A circuit for an oscillator with common-mode resonance includes a first oscillator circuit and a second oscillator circuit coupled to the first oscillator circuit. Each of the first oscillator circuit or the second oscillator circuit includes a tank circuit, a cross-coupled transistor pair, and one or more capacitors. The tank circuit is formed by coupling a first inductor with a pair of first capacitors. The cross-coupled transistor pair is coupled to the tank circuit, and one or more second capacitors are coupled to the tank circuit and the cross-coupled transistor pair. Each of the first oscillator circuit or the second oscillator circuit allows tuning of a respective common mode (CM) resonance frequency (Fcm) to be at twice a respective differential resonance frequency (FD).DM——ITS 62683970-1.093986 0453
