EXPERIMENT NO. 1AIM: To design a c mos inverter on PSPICE and simulate it.
ASHUTOSH SRIVASTAVA
REQUIREMENT : PSPICE software.
THEORY:
CMOS is widely used in digital IC’s because of their high speed, low power dissipation and it can be operated at high voltages resulting in improved noise immunity.The inverter consists of two MOSFETs. The source of p-channel device is connected to+VDD and that of n-channel device is connected to ground. The gates of two devices areconnected as common input.Basically an inverter is an ic that inverts the input given to it

EXPERIMENT NO. 2
ASHUTOSH SRIVASTAVA
AIM: To design a NAND GATE on PSPICE and simulate it.
REQUIREMENT : PSPICE software.
THEORY:
It consists of two p-channel MOSFETs connected in parallel and two n-channel MOSFETs connected in series. P-channel MOSFET is ON when gate is negative and N-channel MOSFET is ON when gate is positive. Thus when both input is low and when either of input is low, the output is high.

EXPERIMENT NO. 3ASHUTOSH SRIVASTAVA
AIM : To design a NOR GATE on PSPICE and simulate it.
REQUIREMENT : PSPICE software.
THEORY:
It consists of two p-channel MOSFETs connected in series and two n-channel MOSFETs connected in parallel. P-channel MOSFET is ON when gate is negative and N-channel MOSFET is ON when gate is positive. Thus when both inputs are high and when either of input is high, the output is low. When both the inputs are low, the output is high.

EXPERIMENT NO. 4AIM: To design a differential amplifier on PSPICE and simulate it.
ASHUTOSH SRIVASTAVA
REQUIREMENT : PSPICE software.
THEORY:
A differential amplifier amplifies the difference between two voltages V1 and V2.The output of the differential amplifier is dependent on the difference between two signals and the common mode signal since it finds the difference between two inputs it can be used as a subtractor. The output of differential amplifier is
