SUMMARY Low Power CMOS Ramp Generator Circuit for DC–DC Converters The proposed and conventional ramp generator circuits for switching regulators are compared in Table I. For the same rising ramp rate and frequency, as required by a PWM DC DC regulator, the proposed ramp generator requires much slower comparators than conventional schemes (20 ns vs. 2 ns). Op amp Integrator, Operational Amplifier Integrator As its name implies, the Op amp Integrator is an operational amplifier circuit that performs the mathematical operation of Integration, that is we can cause the output to respond to changes in the input voltage over time as the op amp integrator produces an output voltage which is proportional to the integral of the input voltage.
