Abstract
PURPOSE:To obtain a frequency dividing circuit operated by a single power supply by feeding back the output of a differential type inverter circuit to an input terminal of the inverter circuit via a 1st transfer gate buffer circuit and a 2nd transfer gate buffer circuit. CONSTITUTION:With the output of a buffer circuit 12 at a low level, when an input clock CK reaches a high level and the 2nd transfer gate TG2 is turned on, the output of the differential inverter circuit 11 reaches a high level after its propagation delay time tpd. In such a case, the 1st transfer gate TG1 receiving an inverted clock signal CK is till turned off and the output of the circuit 12 remains at a low level. When the gate TG1 is turned on, the output of the circuit 12 goes to a high level and, hen the gate TG2 is turned on in such a state, the output of the circuit 11 goes to a low level after the time tpd. The similar operation is repeated every time the gates TG1, TG2 are turned on/off and 1/2 frequency division is implemented.
