Design a nominally 2 V voltage generator that can supply at most 1 µA of DC current (2 MEG resistor). Simulate the operation of your design with SPICE.

Why, in your own words, is it so important for the VCO's center frequency to match the input NRZ data rate when a passive loop filter is used. Use simulations to show the problems. Why does using the active loop filter eliminate this requirement?
