A Differential Active Load and its Applications in CMOS Analog Circuit Designs
نویسندگان
چکیده
In this paper we describe a CMOS differential active load and show how it can be used to create various useful structures. Tunable current gain stages and current squaring circuits are discussed. Their connection to a differential pairbased transconductor results in broad-range tunable transcon ductor structures suitable for adaptive continuous-time filtering applications and a four-quadrant voltage multiplier.
