Problem 12.58

A 741 op amp has a phase margin of 75. If the op amp has nearly coincident second and third poles, what is their frequency?

Step-by-Step Solution:
Step 1 of 3

Post Lab 7: BJT Common­Emitter Circuit Voltage Gain Proposal: This experiment is designed to illustrate how the voltage gain of a CE bipolar transistor circuit can be changed by changing the bias of the circuit and by changing the values of the resistors in the circuit. Experimental Procedure: For the experiment you will require:  1 NPN transistor, either 2N3904, 2N2222, or equivalent  1 Curve tracer  1 Decade resistance box  NI-ELVIS workstation  Resistors and capacitors as noted in the schematic.  Linear graph paper or graphing software (e.g., Excel or MatLab). For part I: Establishing the proper Q-point (1),Use the curve tracer and measure the β of the transistor at a collector current of about 1.0mA and VCE of about 5 V. Set I MAX= 20 ma, V MAX= 10V,
