  1. Solve low-frequency-cutoff problems in capacitive sensors
    One 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...

  2. LC Oscillator has Stable Amplitude
    Many 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,...

  3. Photoresistor provides negative feedback to an op amp, producing a linear response
    Jan Novák Julius Foit
    AGC (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...

  4. AGC amplifier features 60-dB dynamic range
    When 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...
