A sense amplifier suitable for use with a source of binary signals, where one of the signals is "well" defined and the other is "poorly" defined includes a current source for producing a bias current which is of the same polarity as the current produced by the ill defined signal and of amplitude intermediate the amplitude of the currents produced by the ill and well defined signals. The bias current and signal source currents are summed and when applied to an inverter which is precharged to, or close to, its transition point cause the inverter output to respond with approximately equal speed to either of the two binary conditions.
