IPC: H03K3/03
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent the characteristic/performance of entire semiconductor device from being lowered even when the driving power of the semiconductor device is low by composing the FET of any one of P and N channels of a low threshold voltage type MOSFET. SOLUTION: The threshold voltage of P channel FET P12, P22 and P32 and N channel FET N12, N22 and N32 among transistors composing of an inverter ring is made into threshold voltage type MOSFET lower than the threshold voltage of MOSFET used for the other parts. Concerning the power Supply voltage dependency of oscillation cycle of the inverter ring controlled by a constant current, when the power supply voltage is increased, the oscillation cycle is expanded and when the power supply voltage is decreased, the oscillation cycle is reduced. Since the power supply voltage dependency is kept linear even near a lower operating limit voltage, even in the area near the lower operating limit voltage which is disabled for a conventional circuit system, a signal having the suitable timing for the other circuit in the semiconductor device can be provided.
