Patent ID: 7982527

Claim:
A reconfigurable hybrid frequency mixer comprising: a programmable input stage configured to receive an input signal; a programmable mixing core coupled to the input stage and configured to receive the input signal and a local oscillator signal and to generate a mixed signal; a load stage coupled to the mixing core and configured to receive the mixed signal and provide an output signal; and a first switch coupled to the load stage and configured to be actuated by a control signal to couple the load stage to a supply voltage terminal in an active mode of the reconfigurable hybrid frequency mixer and to couple the load stage to a floating terminal in a passive mode of the reconfigurable hybrid frequency mixer; wherein the input stage comprises a transistor circuit having a cascode configuration and a bypass switch; wherein, in the passive mode, wherein the transistor circuit and the bypass switch are configured so that the bypass switch is actuated to bypass the transistor circuit; and wherein the transistor circuit has one of a folded-up cascode configuration and a folded-down cascode configuration.
