Comparators (112, 114) receive portions of the (differential) integrated signal for comparison with a ramp signal from a ramp generator 116.

The integrated circuit further includes feedback circuitry for the ramp generator that maintains a constant ramp slope for the ramp generator.

The ramp generator produces constant slope within each segment regardless of the load condition.

The integrated circuit further includes a ramp generator that provides a voltage ramp to the ADC.

A high speed ramp generator is presented.

The output transistor (T1) provides a ramp shaped output current, under control of a ramp generator (RG).

A ramp generator block (16) provides to the comparator block (14) a first ramp signal for buck mode and a second ramp signal for boost mode.

A voltage ramp generator generates a voltage ramp that has a linear first portion and a non-linear second portion.

Comparators (112, 114) receive portions of the (differential) integrated signal for comparison with a ramp signal from a ramp generator 116.

The device may include a ramp generator, a counter, and/or other components.

A waveform generator produces a plurality of segments of ramp at the output.

The transmitter includes a preamble data generator, a modulator, and a ramp processor.

A digital to analog converter including an input for receiving an input signal, a ramp generator, and a delta-sigma modulator responsive to the input signal and an output of the ramp generator.

The ramp generator can be configured to reset the ramp signal to a specified state in response to an output signal from the second comparator.

The ramp voltage generator can include a capacitor and a digitally controlled current source.
