What Are the Implications of Threshold Voltage Roll Off?
Threshold voltage roll off has several implications:
1. Increased Leakage Current: As Vth decreases, the off-state leakage current increases, leading to higher power consumption. 2. Reduced Noise Margin: Lower Vth can result in reduced noise margins, affecting the reliability of digital circuits. 3. Performance Variability: Variations in threshold voltage can lead to inconsistencies in transistor switching speeds, impacting the overall performance of integrated circuits.
