A Novel Approach for On-chip Step Down DC-to-DC Converter with DC Voltage Control

This paper propose a novel design for an on chip implementation of DC to DC converters. Instead of existing designs approaches which control output voltage using pulse width modulation (PWM) scheme, this design style proposes output voltage control with a DC voltage source. The proposed converter circuit is designed and tested for frequency operations between 50KHz to 50MHz for pulse generation. This frequency range can be further fine tuned as per the specific need of any particular circuit. For MOSFETs we have used industry certified models of 180nm mixed mode planar CMOS technology. Cadence tool kit environment is used for simulating the circuit. Results obtained show that this circuit can be used a potential on-chip dc to dc converter.
