Local oscillator (LO) for wireless communication

Abstract:

Certain aspects of the present disclosure provide a local oscillator (LO) for wireless communication. In some examples, the LO is configured to generate an LO signal by inverting, by a first inverter, a first signal to generate a second signal having a first frequency, the first signal being an oscillating signal. In some examples, the LO is configured to control, using a third signal having a second frequency, a first switch receiving the second signal. In some examples, the LO is configured to control, using a fourth signal having the second frequency, a second switch receiving the second signal, wherein the fourth signal is a complement of the third signal and wherein the second frequency is one-half the first frequency.
