4. A clock signal is routed on the top metal layer using a wire that is 2 µm wide and has a self-heating limit of 20 mA. The wire has a capacitance of 0.6 fF/um and the load capacitance is 115 fF. The clock switches at 1 GHz and has a 10 ps rise time. How far can the wire run between repeaters without overheating? Assume, VDD = 3V. 5. For a certain sequential logic circuit, a 25 MHz clock signal is used. For the timing parameters given below, compute the maximum time that can be borrowed for 2-Phased Latches and Pulsed Latches sequencing methods. Given, tsetup = 12 ns, tnonoverlap = 7 ns, tpw = 30 ns.

6. Sketch a 3-input XOR and a 4-to-1 MUX by applying Transmission Gate and Pass-transistor. Compute the number of transistors required to design those gates. Design and simulate it using the Cadence. 7. Select and analyze a latch that will mitigate all the drawbacks of a transmission gate latch. Distinguish all the delay elements of a flip-flop. 8. A 3-input NAND gate is designed using dynamic logic. Compute the output voltage (Vout) for this circuit when the inputs are 1, 0, 1 (i.e., NMOS2 is receiving 0 input). Design it using the Cadence. Simulate for different input patterns.
