Abstract:
Provided is a modulation-index adjustable amplitude shift keying (ASK) transmitter including: a bias current supply unit supplying one or more bias currents in response to a digital signal that is to be transmitted and one or more bias current control signals; and a modulation signal generator generating a modulation signal corresponding to the digital signal by modulating a carrier signal in response to the one or more bias currents.
