Abstract
A transconductance amplifier has a pair of input terminals and a pair of output terminals. A first pair of transconductors is connected to the input terminals and the output terminals. A second pair of transconductors has inputs connected to output terminals, and outputs connected to the opposing output terminals. A third pair of transconductors has both its inputs and its outputs connected to the output terminals. One or more of the transconductors have a control port for a control signal to adjust its transconductance. The control signal may switch the transconductance of this or these transconductors between two or more values. One or more of the transconductors in the transconductance amplifier may include a tri-state inverter, which may be enabled or disabled through a control port.
