ABSTRACT:
A power supply circuit for a non-threshold logic (NTL) circuit including a plurality of NTL gate circuits, includes a monitoring circuit, a reference circuit and a comparing and regulating circuit. The monitoring circuit outputs a monitor voltage substantially proportional with a first factor to a voltage variation between an NTL lower voltage on an NTL higher power supply line and an NTL higher voltage on an NTL higher power supply line. The reference circuit outputs a reference voltage substantially proportional with a second factor to the voltage variation. The comparing and regulating circuit compares the monitor voltage from the monitoring circuit and the reference voltage from the reference circuit, and regulates the NTL lower voltage in accordance with the comparing result such that the NTL lower voltage is equal to a predetermined voltage.
