PHASE SHIFTER TYPE RC OSCILLATOR

PURPOSE:To facilitate the setting of the constant of an internal element by connecting a phase delay type phase shifter being RC integration circuits via a buffer. CONSTITUTION:A phase delay shifter being RC integration circuits comprising of resistors 1-3 and capacitors 4-6 connected respectively via buffers 9-11 and the RC integration circuit of each stage is handled as one independent circuit without mutual interference. Furthermore, even when the circuit is connected to an output terminal, the effect of the circuit is not required to be considered and when the desired oscillating frequency is obtained, the constants or the internal elements 1-6 have only to be considered for each RC integration circuit, then the constants of the internal elements 1-6 are easily set.
