Frequency multiplying transceiver

摘要

Described herein is a wireless transceiver and related method that enables ultra low power transmission and reception of wireless communications. In an example embodiment of the wireless transceiver, the wireless transceiver receives a first-reference signal having a first-reference frequency. The wireless transceiver then uses the first-reference signal to injection lock a local oscillator, which provides a set of oscillation signals each having an oscillation frequency that is equal to the first-reference frequency, and each having equally spaced phases. Then the wireless transceiver combines the set of oscillation signals into an output signal having an output frequency that is one of (i) a multiple of the first-reference frequency (in accordance with a transmitter implementation) or (ii) a difference of (a) a second-reference frequency of a second-reference signal and (b) a multiple of the first-reference frequency (in accordance with a receiver implementation).
