Unformatted text preview: drain = V gate = 5V b) V source = 0V, V substrate = 1V, V drain = V gate = 5V EECS 170D Homework #1 Due in class Tuesday October 16 th , 2007 #3) Determine all node voltages and currents for the given circuit. Transistors #4a) Determine the drain current and output voltage for the following circuit for V in = 0V and V in = 1.8V. Assume a long-channel device (W = 8 μ m, L = .8 μ m). b) Recalculate the bias point for the above circuit at V in = 1.8V including the effects of velocity saturation. Assume a short-channel device (W = 2 μ m, L = .2 μ m). #5) Derive an expression giving V o as a function of V i ,V TH (V o ) and I o . Then ignoring the body effect, what is the nominal value of the level shift (V i – V o )?...
