Abstract
An apparatus is disclosed for oscillator leakage calibration. In example aspects, the apparatus includes a mixer circuit and calibration circuitry. The mixer circuit has a first stage including at least one transistor coupled between a mixer input and a mixer output and a second stage including one or more transistors coupled between the at least one transistor and the mixer output. The mixer circuit also has tuning circuitry coupled to the at least one transistor. The calibration circuitry includes at least one resistor coupled between a power distribution node and at least one mixer node, with the at least one mixer node coupled between the at least one transistor and the one or more transistors, and at least one switch coupled between the power distribution node and the at least one mixer node. The calibration circuitry also includes controller circuitry coupled between the mixer node and the tuning circuitry.
