Problem 12.70

Consider the equivalent half-circuit shown in Fig. 12.43. Assume that in the original circuit, is biased at a current I, and are biased at 2I, the dc voltage drop across is 0.2 V, and the dc voltage drop across is 0.3 V. Find the open-circuit voltage gain (i.e., the voltage gain for ). Also find the output resistance in terms of I. Now with connected, find the voltage gain in terms of . For , find I that will result in the voltage gains of 160 V/V and 320 V/V.

Transparent D Latch : We store a bit of information using a D latch. A D latch is an S – R latch with D connected to the S input and D’ connected to the R input (this eliminates the troublesome 1 – 1 input combination) When the enable input C is asserted, the latch is said to be “open” and the path from the D input to the Q output is transparent When the enable input C is negated, the latch “closes” - the Q output retains its last value. There are four propagation delay parameters for this D latch and you will measure them in your lab : {Refer to Slide 121 of the PPT Notes for Module 3 for the figure and details of the propagation delays.} There is a window of time around the falling edge of C when the D input does not change. The time prior to this edge that the D input remai
