Title: Oscillator
Inventor: AYUSAWA IWAO
IPC: H04N5/335
Filed: 1985-02-20
Abstract: PURPOSE:To decrease the scale of the circuit by extracting selectively only one phase near a prescribed phase of a reference signal among prescribed oscillation phases of a VCO output at each repetitive period of the reference signal so as to eliminate the need for a frequency divider applying 1/N frequency division to the VCO output. CONSTITUTION:In order to produce a feedback signal 2 from an output 7 of a VCO 6, one pulse edge only of the VCO output 7 near the pulse edges at the repetition of any pulse edge of two kinds of reference pulse edges is selected and the phase of the edge is extracted by a phase extracting circuit 8. The circuit 8 extracts a pulse edge (b) of the output 7 at each repetition of the pulse edge (a) of the signal 1 and produces a pulse 2 having phase information of the edge (b). The pulses 2, 1 are compared by a phase comparator 3 and a comparator output is obtained, where the voltage is at a high level in the phase relation shown in the left in waveform diagram and at a low level with the phase relation shown in the right, and the VCO control voltage 5 is obtained from the said output via an LPF 4.
