Spletback to dc. The demodulator consists of a switch S 2 that is synchronously driven to S 1. An integrator then smooths the switch output and presents the final dc output. The circuit benefits from high overall dc gain and low baseband noise. The dc gain, being the product of the ac stage and the dc gain of the integrator, easily reaches an Splet09. dec. 2015 · It’s necessary because dumping the capacitor directly through the switch produces unwanted high-frequency voltage noise. The simple RC filter here is still only a partial solution, though. If...

This tells us that the current charging the capacitor is proportional to the differential of the input voltage. By integrating Equation 10.2.1, it can be seen that the integral of the capacitor current is proportional to the capacitor voltage. v(t) = …

SpletWhere: ω = 2πƒ and the output voltage Vout is a constant 1/RC times the integral of the input voltage V IN with respect to time. Thus the circuit has the transfer function of an inverting integrator with the gain constant of -1/RC. The minus sign ( – ) indicates a 180 o phase shift because the input signal is connected directly to the inverting input terminal …
