Abstract
This paper presents three pulsewidth modulation modulators using CMOS operational transconductance amplifiers. They consist of a ramp integrator and current-tunable Schmitt triggers. Prototype circuits built using discrete components exhibited that their duty cycles are linearly controllable. Because of their simple structure, the proposed modulators can be easily fabricated in a monolithic integrated circuit.
