This paper describes a technique for compensating for the thermal variation in DC characteristics and propagation delay for GaAs DCFL circuits. This technique controls a voltage with a minus-one slope of the transfer curve by applying the substrate voltage. The experimental circuit demonstrated no degradation in noise margin for the temperature range from 30 to 130°C and the temperature coefficient of the propagation delay for this circuit was as small as +0.19%/°C.
