Abstract

PURPOSE:To obtain a VCO with excellent performance, by providing same resistors between a power supply voltage and a voltage appeared between the source and ground potentials of N channel MISFETs. CONSTITUTION:Same resistors R1-R3 are provided between a power supply VDD and a voltage VRO appeared between the source and ground potential VG of an N channel MISFET-T01, and voltages VB1 and VB2and the VDD are applied to a complementary inverter. Thus, a ring oscillator output Vs is stepped up to the VB1 at the stage of channel type FETs-T61 and T62 and amplified at the stages of T71 and T72 and amplified finally up to the VDD at the stages of T81, T82. Thus, since the VB1 and VB2 are changed in response to the input, i.e., the Vs, the correct circuit operation can be guaranteed.
