For the ADC input impedance, assume the S&H capacitor side of the S&H 6K resistor is connected to ground. Cheers, Hal. 0 Kudos.• Impedance is the relationship between voltage and current –For a sinusoidal input –Z = V/I so for a capacitor, Z = 1/2πFC or 1/j*2πFC • Understand how to use impedance to analyze RC circuits –Compute the “voltage divider” ratio to find output voltage –Calculate series and parallel effective impedancesThe current gain Ai of common collector BJT is given by the ratio of output current IE to input Current IB: IE = IC + IB. Ai = IE / IB. Ai = (IC + IB) / IB. Ai = (IC / IB) + 1. Ai = β + 1. Related Formulas and Equations Posts: Diode Formulas & Equations – Zenner, Schockley & Rectifier.

Any general formula for calculating the input impedance of a circuit is VIN/IIN = ZIN. When the DC bias circuit is active, the transistor has a DC operating point of Q.Non-inverting Operational Amplifier Voltage Follower. In this non-inverting circuit configuration, the input impedance Rin has increased to infinity and the feedback impedance Rƒ reduced to zero. The output is connected directly back to the negative inverting input so the feedback is 100% and Vin is exactly equal to Vout giving it a fixed gain ...

Since the load impedance is a short circuit, and the angle is the equation simplifies to . When we find the input impedance, we can replace the transmission line and the load, as shown in Figure fig:IITRLineEqCirc .

Finding the Input Impedance First we want to find an expression for Zin, the net impedance of the source inductor in the transformer. This impedance is the combined influence of M and LS. We know that whatever Zin is, it must be the “resistance” of the source inductor in the circuit.
