EL ENG 140 Study Guide - Midterm Guide: Pmos Logic, Current Source, Voltage Source
Document Summary
Note: use the device parameters given in class. Vt=+/ -0. 5v, uncox=200ua/v2, upcox=100ua/v2, lambda0=0. 02 1/v: (30pts) design an amplifier with a low frequency gain of at least 100 and a unity gain frequenc y of 5 ghz with a 10pf load . Use an nmos-input common-source amplifier with a pmos current source load. You may use one resistor in your circuit, and assume a 5v supply, but all other devices must be fets (no ideal voltage source, current sources, etc. ). Try to minimize the size width of your transistors. All overdrive voltages (vov or vdsat) must be between 0. 1 and 0. 5 volts. Calculate the values for gm, ro, id, and vdsat that you will use. Draw a schematic of your design and clearly label all components (r= , w/l= ) Fill in the table with the data about each of your fets. Page 1 of 4: (25pts) for the amplifier shown below,
