This paper presents a novel approach of low power differential ramp generator with negative feedback for the compensation of the variations in process, voltage, and temperature (PVT). The derived equations of the prop...
The Programmable Ramp Generator (PRG) peripheral provides voltage ramp signals with no processor overhead. The PRG can produce a falling ramp, a rising ramp or alternating rising/falling ramp triggered from many input...
In this work, we propose a comparator-less Reactive Ramp Generator (RRG) that addresses these problems by offering improved transient response and reduced sensitivity to PVT variations through a novel circuit architecture.
The sweep generator is a gated ramp or sawtooth generator that drives the horizontal deflection amplifier. Ramp generators are also used in magnetically deflected CRT display systems to generate deflection-coil currents.
Ramp signal generators available today are not fully linear. They have some non-linearities due to circuit parameters. This paper is presented with concepts covering the design of adaptive ramp generators with high- q...

The ramp compensator 106 measures an on-ramp slope of a sensed current indication, infers an off-ramp slope, and adaptively adjusts a slope compensation signal slope to track changes in the...
This autotuning of the external ramp generator provides immunity of quality factor change under variations of duty cycle, component values of topological change of the power converter.
For current-mode controlled SMPS application the PRG can satisfy the function of slope compensation and for a voltage-mode controlled SMPS the function of sawtooth signal.
