Question:

The circuit in Figure P16.77 is a form of clocked shift register. Signals $\phi_{1}$ and $\phi_{2}$ are nonoverlapping clock signals. Describe the operation of the circuit. Discuss any possible relationship between the width-to-length ratios of the load and driver transistors for "proper" circuit operation.
