    Figure P2.86 shows a circuit that performs a low-pass STC function. Such a circuit is known as a first-order, low-pass active filter. Derive the transfer function and show that the dc gain is (-R2/R1) and the 3-dB frequency wo=1/CR2. Design the circuit to obtain an input resistance of 10kOhms, a dc gain of 40 dB, and a 3-dB frequency of 1kHz. At what frequency does the magnitude of the transfer function reduce to unity? You should do this one using the "virtual ground" technique to keep the analysis simple. Please simulate the frequency response of the circuit in PSPICE and include an annotated graph and write some observations about it.

    Figure P2.86 pretexts a circumference that performs a low-pass STC administration. Such a circumference is disclosed as a first-order, low-pass free depurate. Derive the convey administration and pretext that the dc fashion is (-R2/R1) and the 3-dB quantity wo=1/CR2. Design the circumference to accomplish an input opposition of 10kOhms, a dc fashion of 40 dB, and a 3-dB quantity of 1kHz. At what quantity does the magnitude of the convey administration bring to singleness? You should do this single using the “virtual ground” technique to tend the decomposition incomplex. Please impersonate the quantity rejoinder of the circumference in PSPICE and include an annotated graph and transcribe some observations environing it.
