Abstract: An electronic device includes a first sample circuit configured to generate a first sampling signal by sampling an input signal in response to edges of a clock signal, a first comparator configured to generate a first logic decision signal by comparing a voltage level of the first sampling signal with a reference voltage level, an analog bang-bang phase detector configured to generate a first detection signal by executing an exclusive OR (XOR) operation on successive samples of the first logic decision signal, and a digitally controlled oscillator configured to vary a frequency of the clock signal according to the first detection signal.

Abstract: An amplification circuit includes an amplifier comprising an input terminal and an output terminal, a first inductor unit connected to the input terminal, and a second inductor unit connected to the output terminal. The first inductor unit and the second inductor unit may be inductively coupled to each other so that a change in output voltage of the amplification circuit is positively fed back.
