Abstract
An amplitude shift keying (ASK) demodulator and a communication apparatus including the same are provided. The ASK demodulator includes an envelope detector, a clock generator, a plurality of elementary demodulators, and a post signal processor. The envelope detector is configured to detect an envelope of an ASK modulated signal and to generate an envelope signal. The clock generator is configured to generate a main clock signal and first through n-th clock signals, where n is a positive integer of at least 2. The plurality of elementary demodulators are each configured to sample the envelope signal using a first sampling clock signal and a second sampling clock signal, and to output first through n-th elementary demodulated signals based on a difference between the sampled envelope signals using the first sampling clock signal and the second sampling clock signal. The post signal processor is configured to generate a final demodulated signal using at least one of the first through n-th elementary demodulated signals.
