What are the advantages of NMOS inverter with active load?

Inverter with N type MOSFET Load The main advantage of using MOSFET as load device is that the silicon area occupied by the transistor is smaller than the area occupied by the resistive load. Here, MOSFET is active load and inverter with active load gives a better performance than the inverter with resistive load.

Which type of resistive load is used in resistive inverter?

Figure 1: Resistive-load inverter circuit Here an enhancement-type nMOS transistor acts as the driver device. The load consists of a simple linear resistor, RL. The power supply voltage of this circuit is VDD.

What is the value of VOH for a resistive load inverter?

Thus, the VOH level is equal to VDD, resulting in higher noise margins compared to saturated enhancement-load inverter.

What is the transition point of an inverter?

Explanation: For 8:1 inverter the logic 0 to 1 transition delay can be given as 21Ʈ and logic 1 to 0 transition delay can be given as 2(1/3)Ʈ. Explanation: The area of a basic CMOS inverter is proportional to the total area occupied bu the p and n devices (WpLp + WnLn).

What is the transition point of an inverter Sanfoundry?

Explanation: 8:1 nMOS inverter allows stray and wiring capacitance and the logic 1 to 0 transition delay can be given as 1Rs x 5 square Cg which gives 5Ʈ. Explanation: For 8:1 inverter the logic 0 to 1 transition delay can be given as 21Ʈ and logic 1 to 0 transition delay can be given as 2(1/3)Ʈ.

Which is better inverter with MOSFET or resistive load?

The main advantage of using MOSFET as load device is that the silicon area occupied by the transistor is smaller than the area occupied by the resistive load. Here, MOSFET is active load and inverter with active load gives a better performance than the inverter with resistive load.

What is the structure of a resistive load inverter?

The basic structure of a resistive load inverter is shown in the figure given below. Here, enhancement type nMOS acts as the driver transistor. The load consists of a simple linear resistor R L. The power supply of the circuit is V DD and the drain current I D is equal to the load current I R.

What are the advantages of a depletion load inverter?

The advantages of the depletion load inverter are – sharp VTC transition, better noise margin, single power supply and smaller overall layout area. As shown in the figure, the gate and source terminal of load are connected; So, V GS = 0. Thus, the threshold voltage of the load is negative. Hence,

Which is the saturated enhancement load inverter in VLSI?

The saturated enhancement load inverter is shown in the fig. (a). It requires a single voltage supply and simple fabrication process and so V OH is limited to the V DD − V T. The linear enhancement load inverter is shown in the fig. (b). It always operates in linear region; so V OH level is equal to V DD.
