Inductor based switching mixer circuit
Abstract:
A switching mixer that includes an input configured to receive a radio frequency (RF) signal, a set of inductors, and a set switches in a one-to-one relationship with the set of inductors. The set of switches are configured to alternate turning off in a quadrature sequence of a switching cycle. When a respective switch of the set of switches is turned off: the respective switch connects the input to a respective inductor of the set of inductors to convert the RF signal to a baseband current; and each remaining inductor of the set of inductors is configured to maintain current therein.
