A voltage-controlled oscillator includes a delay circuit. The delay circuit includes a first buffer inverter which receives one of the differential input signal and outputs an other of the differential output signal, a second buffer inverter which receives the other of the differential input signal and outputs the one of the differential output signal, a first latch inverter which receives the one of the differential output signal, and includes an output connected to an output of the first buffer inverter, and a second latch inverter which receives the other of the differential output signal, and includes an output connected to an output of the second buffer inverter. The first latch inverter and the first buffer inverter receive a current produced from different voltage-current conversion circuits.
