Summary:
This paper presents a novel low power analog to digital interface (ADI) for digitally controlled DC-DC Converter. The whole ADI has been implemented in commercial 0.18 μm CMOS process design kit. Simulation results validate the design concept. The proposed ADI consumes 7.5 μA current under 1 V supply voltage with 500 KHz sampling rate and 4-bit resolution. It is very suitable for digitally controlled pulse width modulation (PWM) mode DC-DC converter.
