ABSTRACT:
An improved voltage comparator for use in waveform characterization and like applications is disclosed. The current drawn through two matched transistors connected to a source of current is measured to determine whether a reference signal applied to the base of a first reference transistor is greater or less than the signal to be measured applied to the base of the other transistor. Current is only drawn through the two transistors at times corresponding to desired sampling times, substantially eliminating differential heating effects. The comparator provides substantially reduced settling times, resulting in reduced distortion of the waveform.
