Oscillator using a time constant circuit based on cyclic heating and cooling

摘要

A clock generator or oscillator circuit for use in an integrated circuit for generating a clock signal includes a 555 timer circuit. The time constant circuit of the 555 timer includes a heater element for generating heat and a transducer for converting heat generated by the heater element into electrical energy. The clock signal is generated in response to the heating and cooling of the heater element.
