A Transconductor and Tunable $G_{m}-C$ High-Pass Filter Linearization Technique Using Feedforward $G_{m3}$ Canceling

Abstract

A linearization technique of a transconductor circuit is proposed in this brief. By adopting a two-path feedforward architecture, the Gm3 component of the transconductor vanishes and a highly linear V-to-I conversion is achieved. This technique consists of self-biased inverters only, and it can be applied to transconductors with differential inputs. It also… (More)
