In this paper a new approach for a Pulse Width Modulation (PWM) circuit operating in current-mode using a CMOS classifier core circuit, and its application to level crossing are presented. The proposed architecture is much simpler than existing PWM methods and the generated PWM signal can be controlled electronically through the control currents of a core circuit. Measurements performed with DU-TCC 1209, an IC designed and manufactured using 0.35 μm AMS technology parameters, show a perfect match with theoretical results.
