Figure 1 is the 90°phased separation circuit. It is a phase separation circuit formed by two circuits with the output phase difference keeping the same, it is used as a standby circuit of the variable frequency two phase oscillator or the basic signal source of the two phase lock-in amplifier. The circuit will offset 90 ° phase frequency into 8 sections, which are: f1=331.7KHz，f2=37.92KHz，f3=7.5799KHz，f4=1.4115kHz，f5=90.62kHz，f6=16.875KHz，f=3.372KHz，f=0.38561KHz.
