ABSTRACT:
The present invention provides a transconductor for allowing a user to adjust the transconductance of the transconductor having wide linear input range and large output resistance and the transconductor for processing high frequency signals includes an input portion for receiving at least one input signal and generating a primary current in response to the input signal; a programmable bias unit for providing a bias current to the input portion; a current mirror unit for generaing a secondary current by mirroring the primary current; and at least one output terminal for providing one or more of output signals in response to the secondary current.
