Inductive Sensor with Demodulator
A transconductor converts voltage on an inductive sensor to a proportional current using two "coupling" capacitors. Responsive to movement of an electrically conductive target from the null position a resonant current is formed between the two sensor coils. A single differential transistor...

| description | A transconductor converts voltage on an inductive sensor to a proportional current using two "coupling" capacitors. Responsive to movement of an electrically conductive target from the null position a resonant current is formed between the two sensor coils. A single differential transistor pair switched by periodic drive signals commutes the net alternating current at the single input to direct current. |
