摘要
An improved programmable transconductor can be efficiently implemented utilizing a programmable resistor circuit that allows for only a selected portion of the resistor circuit (associated with a desired transconductor gain) to be coupled between summing nodes of the transconductor. Additional switching circuits can be used to reduce gain errors associated with the switches used to implement the aforementioned solution. Additionally, the improved programmable transconductor can be integrated into fully differential programmable analog integrated circuits, thereby enhancing the performance of such integrated circuits.
