4 cards from this section. Quick, good the night before a test.
Define propagation delay.
Think about how long it takes for an action to result in a reaction.
What does static power mainly depend on?
Reflect on what occurs when the circuit is not in operation.
What is the primary component measured by propagation delay?
Remember, it's related to how long it takes for a signal to propagate through a circuit.
True or False: Static power is always higher than dynamic power in CMOS circuits.
Consider when does power actually flow in a CMOS circuit.
Consider a CMOS circuit with three stages of logic gates, each with a identified propagation delay of 1.2 ns, 0.8 ns, and 1.5 ns. Calculate the total propagation delay for the circuit.
Simply add the delays from each gate.
A CMOS circuit operates with a supply voltage of 1.8V and a load capacitance of 15nF. If it switches at 1 MHz with a switching activity factor of 0.2, calculate the dynamic power consumption.
Remember to convert the units correctly.
