Abstract
A transconductor circuit, including a differential transconductor amplifier circuit. The transconductor circuit includes an input pair of transistors adapted to receive a differential input voltage, as well as a pair of output terminals adapted to provide a differential output current. A second pair of transistors provides current to the input pair of transistors. A floating voltage circuit is adapted to generate a floating voltage corresponding to a common-mode voltage of the differential output nodes and to control the second pair of transistors in response to the floating voltage to stabilize the common-mode voltage of the differential transconductor amplifier circuit.
