CR oscillating circuit
 There is provided a CR oscillating circuit from which oscillation frequency is obtained as targeted, when MOS capacitors having large voltage dependency are used therein. The circuit is constructed such that bias voltage is applied always to the two MOS capacitors by connecting the two MOS, capacitors in series in the opposite direction from each other and by connecting further a MOSFET.
