Comparison of Hysteresis margin and Hysteresis width Schmitt Trigger Oscillators using logic gates in 28nm CMOS Technology

This study compares two Schmitt trigger circuits with different parameters of the circuits like higher threshold and lower threshold. This configuration utilizes the properties of NAND gates to create a hysteresis effect, allowing for noise filtering and reliable threshold-based switching. The Schmitt trigger is commonly used in digital circuits, such as in the design of oscillators, waveform generators, and pulse generators. The 28 nm CMOS technology’s Cadence and model parameters are employed to evaluate the recommended circuits’ performance.
