Apparatus and method for variable gain transconductance










Image Number 10 for United States Patent #8106710.

The present disclosure describes a variable gain transconductor having gain and/or linearity performance that are selectively controllable in operation. In one embodiment the gain and/or linearity performance are selectively controllable in response to the strength of an input signal, such as an incoming radio frequency (RF) signal to a radio receiver. In one embodiment, gain and/or linearity performance of the variable gain transconductor are selectively controllable by selecting or deselecting a number of operating bias cells. In one embodiment, gain and/or linearity performance of the variable gain transconductor are selectively controllable by selecting or deselecting a number of operating transconductance (gm) cells. In one embodiment, gain and/or linearity performance of the variable gain transconductor are selectively controllable by selecting or deselecting a combination of operating bias cells and gm cells. In one embodiment, the variable gain transconductor is configured to convert single-ended voltage input into a differential current output. In one embodiment, the variable gain transconductor is configured to convert differential voltage input into a differential current output.
