ABSTRACT:
The circuit compensates for the difference in the source impedances of signal and reference generating circuits whose outputs are coupled to a sense circuit which loads (draws current from) the signal and reference generating circuits. The signal generating circuit has a source impedance (R.sub.1) and produces either one of two (V.sub.1H or V.sub.1L) output signal levels which is coupled via a first transmission gate having an "ON" impedance R.sub.2 to a first input terminal of the sense circuit. The reference generating circuit has a lower source impedance (R.sub.3) than the signal source and produces an output intermediate the two signal levels which is coupled via a second transmission gate having an "ON" impedance R.sub.4 to a second input terminal of the sense circuit. The reference voltage applied to the second input of the sense circuit is maintained at a predetermined level between the high and low levels of the signal applied to the first input of the sense circuit, by making the sum of R.sub.3 and R.sub.4 proportional to the sum of R.sub.1 and R.sub.2 .
