ABSTRACT:
The invention relates in general to error correcting programmable pulse generator, and more particularly to a programmable pulse generator that removes errors due to manufacturing tolerances, power supply variation, and temperature. A method of modifying a signal from a source includes generating a signal and varying a first and second impedance to control the rise and fall time and average level of the signal to produce an output signal, wherein a plurality of voltage levels are modified. Then, varying a first reference current to produce a second reference current that provides a source for a plurality of currents, wherein the plurality of currents includes a first current, a second current and a third current. In addition, scaling the second reference current producing the first current, second current and third current to correct the plurality of modified voltage levels, wherein errors induced by an external environment and manufacturing tolerances are reduced.
