WebQuestion: For the feedback amplifier in Fig. P11.68, select a value for R_F that results in a closed-loop gain A_f = V_0/I_S -10 k Ohm. Then, analyze the circuit to determine the actual value of A_f realized. As well, determine R_in and R_out. Transistors Q_1 and Q_2 are operated so that g_m1 = g_m2 = 4 mA/V and r_o1 and r_o2 can be neglected.

WebIn electronic amplifiers, the phase margin (PM) is the difference between the phase lag φ (< 0) and -180°, for an amplifier's output signal (relative to its input) at zero dB gain - i.e. unity gain, or that the output signal has the same amplitude as the input. = (). For example, if the amplifier's open-loop gain crosses 0 dB at a frequency where the phase lag is -135°, …
WebAfter this time, the percentage of drift will steadily decrease to less than 0.02% per minute. When used in closed-loop control, piezo drift is dramatically reduced to maintain position as long as the system is under power. open-loop drift over a 10 minute period. Open-loop systems have lower noise (and resolution) than a closed-loop system ...
