Document Summary
Sid__________________________: [4] a single-pole amplifier has a low frequency gain magnitude of 10,000 and a gain magnitude of 10 at 10. What are the pole and unity gain frequencies? fp = 10mhz/(10k/10)=10khz; fu = 10mhz*10=100mhz. /59: [8] you have made a new 3-terminal device from dna and carbon nanotubes. With one terminal grounded, you determine that the output current in the device follows the equation ib=i0 va. Vb large (10v) , va small (2v: [15] you have an nmos-input common source amplifier with a pmos load. Both transistors are biased in saturation, and the quadratic model is appropriate. The magnitude of the gain is large (>100). You try two independent changes to the circuit: doubling the current by changing the bias voltages, and doubling the length of both transistors without changing anything else. Case 2: [12] fill in the following table for a single-pole amplifier.
