Abstract
A programmable linear transconductor circuit is disclosed. The programmable linear transconductor circuit includes a first current source and a second current source, a first group of transistors and a second group of transistors, a first load coupled to the first group of transistors, and a second load coupled to the second group of transistors, and a first group of switches and a second group of switches. Each switch in the first group of switches is selectively connected to a transistor from the first group of transistors to the first current source or the second current source. Similarly, each switch in the second group of switches is selectively connected to a transistor from the second group of transistors to the first current source or the second current source, accordingly.
