Abstract: Schmitt trigger device is mostly used in analogue and digital circuit as a wave-shaping device to resolve the noise problem, widely used to drive the load with fast switching low-power loss and low-power supply. Conventional Schmitt trigger provides more leakage power, so 4T Schmitt trigger overcomes this problem by using the Self-Controllable Voltage Level (SVL) techniques. The main purpose of this paper is to present the performance factor of Schmitt trigger by applying U-SVL and L-SVL and both technique. The simulation results perform in cadence tool and reported that static power (3.98 fW), dynamic power (38.04 pW), propagation delay (6.13 psec), hysteresis width (0.877 V), voltage gain (30.03 dB), periodic jitter (80 ns), frequency jitter (24.26 kHz), efficiency (63.06%), spectral power (5.388 aW), transconductance (7.17 × 10−14 S) and the total leakage power of individual transistors (1.17 pW) improve using both U-SVL and L-SVL techniques simultaneously with nanoscale measurement with supply voltage Vdd=0.7 V.
