Open the CIPO recordAbstract From the Canadian patent
An oscillation circuit comprises an oscillator including a CMOS inverter, a feedback reactance connected between the input and output terminals of the CMOS inverter and a CMOS transfer gate connected as a feedback resistor between the input and output terminals of the CMOS inverter, a power source terminal section to which an external voltage is applied, and a power control unit for converting the external voltage to a first internal voltage which is supplied as a power source voltage to the CMOS inverter. In the oscillation circuit, the power control unit converts the external voltage to a second internal voltage independently from the first internal voltage and supplies the second …
