RING OSCILLATOR CIRCUIT

摘要

If a low signal being supplied in a gate between transistors MP1 and MN1, a P-type transistor MP1 is turned on to supply the charges to an output node N2; here, when the circumferential temperature of a chip is higher than the critical temperature, the current flowing through a PMOS transistor MP2 is increased and charges up the charges to an output node N2 rapidly compared with the low temperature situation; while the circumferential temperature of the chip is lower than the critical temperature, the current flowing through a PMOS transistor MP2 is decreased and charges up the charges to the output node N2 slowly compared with the high temperature situation.
