Abstract

An apparatus for generating a pulse at a particular time dictated by an input. The apparatus may comprise an offset voltage generator for generating an offset voltage that is a function of the input, a current generator for generating a current, a ramp voltage generator for generating a ramp voltage having an initial value as a function of the offset voltage and a slope as a function of the current, and a pulse generator for generating a pulse in response to the ramp voltage reaching a threshold voltage. With this configuration, the time the pulse is generated is controlled by the input. This may be used in transceivers to control the time of transmission and the time of reception. Such times may be used to set up communication channels, such as ultra-wide band (UWB) channels, for communicating with other devices.
