Abstract
A frequency generator is disclosed including a plurality of inverters employing the gate of a PMOS and NMOS as their common input, and employing the source of the PMOS and drain of the NMOS as their common output, the plurality of inverters being serially connected, the output node of the output inverter being connected to the input node of the input inverter; and a current mirror consisting of two transistors having the same electrical characteristic, the current mirror being connected to the source of the NMOS of the input inverter, a signal transmission delay time of the current mirror being controlled by a predetermined current value applied from an external current source.
