Abstract
A radio frequency (RF) transceiver includes a first oscillator configured to generate a first oscillation frequency associated with an RF signal, a second oscillator configured to generate a second oscillation frequency associated with a clock frequency, a counter configured to generate a counter output signal using the first oscillation frequency and the second oscillation frequency, and a comparer configured to generate a digital output signal associated with the RF signal by comparing an output value of the counter output signal to a reference value.
