Abstract:
An image frequency rejection mixer has a first differential transconductor that receives a differential mixer input signal, a second differential transconductor that receives the differential mixer input signal and cross-coupled to the first differential transconductor, a first mixing circuit that generates a first differential mixing circuit output signal by mixing a first differential information signal with a first local oscillation signal, a second mixing circuit that generates a second differential mixing circuit output signal by mixing a second differential information signal with a second local oscillation signal, with the first local oscillation signal and the second local oscillation signal being in quadrature, and an image rejection circuit that generates a differential mixer output signal from the first and second differential mixing circuit output signals.
