Compact, Four-Quadrant Lock-In Amplifier Generates Two Analog Outputs
Marco Girolami Stefano Salvatori
Generate a pair of quadrature-phase digital signals. The circuit in this Design Idea realizes a simple, low-cost lock-in amplifier employing an Analog Devices AD630 balanced modulator-demodulator IC (Reference 1). The device uses laser-trimmed thin-film resistors, yielding...
