This design idea presents a practical circuit that implements synchronous detection to amplify small DC voltages with high linearity and excellent noise immunity. Such circuits are required in ...

Analog Devices is aiming at low-power signal measurement with a combined synchronous demodulator and filter chip which allows precision magnitude and phase measurements to be made on analogue signals ...

Prepped for synchronous laser-beam detection applications such as print-start timers, the S9684 and S9684-01 photo ICs report highly stable digital outputs even when laser power or ambient temperature ...
