Design of XOR, XNOR Gates using SPICE Code
- Introduce delays in the XOR circuit and analyze the impact on the output waveform. Experiment with different delay values and observe changes in signal timing.
- Modify the existing XOR circuit to implement a half-adder using SPICE. Include inputs for two bits and outputs for both the sum and carry.
- Combine multiple XOR and XNOR circuits to create a 4-bit binary adder. Simulate the addition of two 4-bit binary numbers and analyze the output.
- Design a 2-bit magnitude comparator using XOR and XNOR gates. Simulate the circuit and verify its correctness for all possible input combinations.
- Investigate how temperature variations affect the performance of the XOR and XNOR circuits. Simulate the circuits at different temperature levels and analyze any variations in output.
