An amplifi er with a dc gain of 20,000 V/V and three pole frequencies at 100 kHz, 3 MHz, and 5 MHz is operated in negative feedback with 5 1 V/V. (a) Sketch and label the linearized Bode plot of gain magnitude for a visual estimation of fx and x, and verify that the circuit is unstable. (b) Given that the fi rst two poles are produced at the input and output nodes of an internal transistor amplifi er with a dc gain of 2200 V/V and input-node and output-node resistances R1 5 100 kV and R2 5 10 kV, fi nd the capacitance Cc that, connected across the terminals of this internal stage, stabilizes the circuit for m 5 458. (c) Calculate gm, C1, and C2. What are the values of the new pole frequencies as well as the RHP zero frequency? Use these values to obtain an expression for T(jf).
