- Solve low-frequency-cutoff problems in capacitive sensorsOne of the first problems a capacitive-sensor analog designer must face is the low-frequency cutoff. Theoretically, you must fulfill just one simple requirement: a sufficiently large input resistance of the...Jul 26, 2023
- LC Oscillator has Stable AmplitudeMany applications call for wide-range-tunable LC oscillators that can deliver a nearly constant-frequency, nearly harmonic-free output even when the circuit's output load changes. From a design viewpoint,...Mar 13, 2022
- Photoresistor provides negative feedback to an op amp, producing a linear responseJan Novák Julius FoitAGC (automatic-gain-control) amplifiers use the nonlinear characteristics of control devices. The magnitude of the real component in some of their differential parameters changes depending on variations in their dc...Feb 24, 2022
- AGC amplifier features 60-dB dynamic rangeWhen processing signals from analog sensors, you frequently encounter wide variations in attenuation among communication channels or sensors. Or, you face situations in which several identical sensors within a...Feb 17, 2022
