CMOS threshold voltage (Vth) is the minimum gate-to-source voltage required to create a conductive channel between the source and drain terminals in a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor). It determines the switching behavior of the transistor, influencing its on/off states. If the gate voltage exceeds Vth, the transistor turns on, allowing current to flow; if not, it remains off. The threshold voltage is critical in defining the performance and power consumption characteristics of CMOS circuits.

How threshold voltage depends on the biasing of substrate?
The threshold voltage (V_th) of a MOSFET is influenced by the biasing of the substrate, or body, due to the body effect. When a negative voltage is applied to the substrate relative to the source, the depletion region widens, effectively increasing the threshold voltage. Conversely, if the substrate is biased positively, the threshold voltage decreases. This modulation of V_th through substrate biasing allows for better control of the device's electrical characteristics.
Why substrate in nmos connected to ground and pmos connected to vdd?
In CMOS technology, the NMOS transistor's substrate is connected to ground to prevent parasitic effects and ensure proper operation, as it helps maintain a lower threshold voltage for the NMOS. Conversely, the PMOS substrate is connected to VDD to keep its threshold voltage stable and ensure that the PMOS operates correctly in the enhancement mode. This arrangement minimizes unwanted channel formation and enhances performance by reducing leakage currents in both types of transistors.
What is MTCMOS?
MTCMOS stands for multi threshold CMOS. CMOS stands for complementary Metal Oxide Semiconductor.
What is the abbribiation of cmos voltage level?
The abbreviation for CMOS voltage level is typically referred to as "V_CMOS." CMOS, which stands for Complementary Metal-Oxide-Semiconductor, operates with specific voltage levels for logic high and low, commonly ranging from 0 to the supply voltage (e.g., 3.3V, 5V). The exact voltage levels can vary depending on the technology and application.

Why is a Schmitt trigger called a regenerative comparator?
A Schmitt Trigger is a comparator, because it compares its input voltage to a "threshold" voltage, but it has _two_ threshold voltages (the upper and lower trigger voltages), and which threshold voltage is used depends on the output state. If the input voltage is higher than the upper trigger voltage, the output will be high (for a non-inverting Schmitt trigger). In this state, the input is compared to the lower threshold voltage, so the input now has to go below the lower threshold voltage before the output will go low. The threshold voltage depends on the output state, such that a high output selects the lower threshold voltage, and a low output selects the upper threshold voltage. This can be visualised as using a fixed threshold but adding a small voltage (the difference between the upper and lower threshold voltages, also called the hysteresis voltage) to the input voltage before it is compared. This small added voltage is high when the output is high, and low when the output is low. A small amount of the output voltage is effectively being added to the input voltage before it is compared to a fixed threshold. This is positive feedback, also called regenerative feedback. So a Schmitt trigger operates as a voltage comparator, and a small amount of the output is added to the input, so it uses positive or regenerative feedback.
