CLOCK SUPPLY CIRCUIT FOR LOGIC CIRCUIT OF OTHER SOURCE SUPPLY

摘要

The circuit with simple structure includes a first power source(VDD1), a clock generator(50) generating the clock with specific frequency, first(61) and second(62) logic circuits receiving the clock, and a leakage current cutting-off circuit(70) connected between the second logic circuit and the junction of the clock generator and the first logic circuit. The leakage current cutting-off circuit includes a second power source(VDD2), a diode(D1), a resistor(R4), and a buffer(IC11).
