Determine the equivalent transconductance (Gm), output impedance (Rout) and voltage gain (AV = Vout/Vin ) of circuits shown below. Assume VA = ∞ and equal βs for npn and pnp transistors. (use gm, rπ, β) (a) (b)
Consider the circuit shown in the diagram below. The potential difference across the points a and b is ΔV = 120.0 V and the capacitors have the following values: C1 = 14.0 μF, C2 = 2.00 μF, C3 = 9.00 μF, and C4 = 18.0 μF. Initially the capacitors are all uncharged. mC (b) What is the charge on each fully charged capacitor? Q1 = mc Q2 = mc Q3 = mc Q4 = mc
10.33. Consider the differential pair illustrated in Fig. 10.70. Assuming perfect symmetry and VA = ∞, (a) Determine the voltage gain. (b) Under what condition does the gain become independent of the tail currents? This is an example of a very linear circuit because the gain does not vary with the input or output signal levels.
