In CMOS inveter with Vdd as 5V , if Vin is 2.5 V which of the follwing is true . Assume Vthn = 0.7 and Vthp = -0.7

The CMOS inverter is a digital logic gate that inverts the input signal. It consists of a PMOS transistor and an NMOS transistor. The PMOS transistor is on when the input voltage (Vin) is low, and the NMOS transistor is on when the input voltage is high.

Given the threshold voltages (Vthn for NMOS and Vthp for PMOS), we can determine the state of the transistors:

1. If Vin > Vthn, the NMOS transistor is on.
2. If Vin < -Vthp, the PMOS transistor is on.

Given that Vin = 2.5V, Vthn = 0.7V, and Vthp = -0.7V:

1. Since 2.5V > 0.7V, the NMOS transistor is on.
2. Since 2.5V is not less than -0.7V, the PMOS transistor is off.

Therefore, the output voltage (Vout) will be close to 0V (logic 0), because the on-state NMOS transistor will connect the output to ground.

Please note that this is a simplified explanation and actual CMOS behavior can be influenced by many other factors like noise, temperature, etc.
