CMOS integrated circuit and timing signal generator using same

Claim 1

A timing signal generator, comprising: a timing generator block for producing timing signals of specified delay timings by adding the specified delay timings to input clock signals; a control logic block for providing timing data specifying said delay timings to the timing generator block for controlling the delay timings of the timing signals; a heater circuit for generating heat based on heater current flowing there through to raise temperature of said timing generator block; a heater control circuit for detecting an amount of total electric current flowing through the timing generator block, the control logic block, and the heater circuit and providing a control voltage to the heater circuit based on the amount of total electric current detected to control the heater current flowing through the heater circuit through a negative feedback loop; wherein the heater circuit, the timing generator block and the control logic block are provided within a common CMOS integrated circuit, thereby maintaining constant total electric current in the CMOS integrated circuit.
