Abstract
A new circuit for generating amplitude shift keying, frequency-shift keying, phase-shift keying, and quadrature amplitude modulation (QAM) waves is proposed. The proposed circuit is built around multiple-output operational transconductance amplifiers and a number of digitally controlled switches. Simulation results which confirm the validity of the circuit are included
