ABSTRACT:
A compensating upshift circuit providing low signal degradation and operating at high speed and at low power. Capacitor shunted diodes cross-couple the collectors and bases of two transistors. The cross-coupling eliminates signal swing degradation in the upshift circuit and controls current through the two collector resistors. Equalized collector resistor current eliminates signal swing degradation while providing an upshift circuit with short delays. The capacitor shunted diodes can be replaced by diode connected transistors configured to provide the necessary collector-base capacitance.
