ABSTRACT:
A semiconductor circuit of a current mode type logic is provided having a reference voltage generating circuit which generates the reference voltage to be applied to the logic circuit in response to a clock signal to latch the state corresponding to an input signal at an instant of the clock signal input. The reference voltage has three levels in response to the voltage levels of the clock signal and the input signal: a middle voltage between the two high and low voltage levels of the input signal when the clock signal is at a first level voltage; a voltage higher than the high voltage level of the input signal when the clock signal is at a second level voltage and the output signal is at a high voltage; and a voltage lower than the low voltage level of the input signal when the clock signal is at a second level voltage and the output signal is at a second level voltage and the output signal is at a low voltage. This semiconductor circuit can relax restrictions on the signal amplitude due to the supply voltage and the saturation of the transistors, and, accordingly, allows processing signals having a much greater amplitude than was previously possible.
