CMOS Inverter
How to manufacture the CMOS inverter?
linzmath
- Oct 30th, 2008
It can be made by using pmos and cmos in series. Both gate are connected together and act as input. Source of pmos is connected to supply. drain of?pmos is connected?to drain of nmosand it serves as output. source of nmos is grounded.

Synchronous circuits have common clock and operate utilizing the same. Whereas a aynchronous circuits have different clock frequencies and operate without mutual co-ordination.

All the inputs are feed at the rising or falling end of the clock signal. This makes the circuit to perform task in sync. so that the functional integrity of the logic device is as expected.

FET Voltage Control Device
Why FET is known as voltage control device?
Dipankar Golder
- Oct 26th, 2009
Since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain so it is known as voltage controlled device.For example: In a MOSFET, the current from drai...

- Aug 7th, 2010
TRANSDUCER: A transducer is a device that convert one form of energy into other form of energy.??TRANSPONDER: A transponder is a combination of transmitter+receiver. it receives the weak incoming signal, amplifies it and again transmit the signal. It is mainly used in satellite communication.?

IC Basics
The function of a transistor used in any of the ICs is to perform SWITCHING action and not AMPLIFICATION.Then why DIODES are not used instead of TRANSISTORS as diodes also exhibit the same switching action?

I agree Digital ICs use transistors as switches. But Analog (Linear) ICs Do Use transistors as Amplifiers. Consider the differential pair of transistors that form the front end of an op amp.&nbs...

- Aug 29th, 2010
I tried to measure ring voltage, and showed inside the house 34V A/C, but measuring at the NID seems to show 10V? and change. Maybe caller-ID messes up the signal? Line is -51V DC. DSL is on the same line and is perfect 6016/768 and call quality is clean.

Fermi level for an Intrinsic Semiconductor
Fermi level for an intrinsic semiconductor lies midway between the valence and conduction bands, bcoz---a) the temperature does not influence its position.b) the effective mass of hole is greater than that of electronc) the effective mass of electron is taken equal to that of holed) none of the abovewhich is the right option?

C)..as a intrinsic semiconductor will have 4 electrons..so its neither a acceptor or a donar..

Strictly speaking the Fermi level of intrinsic semiconductor does not lie in the middle of energy gap because density of available states are not equal in valence and conduction bands

Effect of Increased Resistance
What is the effect of increase resistance on reluctance?
ashim_stifler
- Mar 23rd, 2011
The rate of flow of charge(called as current) is inversely proportional to the resistance of the conductor through which the current is flowing in a particular direction. i.e. when we increase the res...

Problem: 1. 1100v, 50Hz,delta connected induction motor has a star connected slip ring rotor with stator to stator transformation ratio of 3.8 . the rotor resistance and stand still reactance are 0.012 ohm and 0.25 ohm. Neglecting stator impedance and magnetizing current determine:
i. Rotor current and power factor at start with slip rings shorted.
ii. Rotor current and power factor at 4% slip with slip rings shorted.
iii. External rotor resistance per phase to obtain a starting current of 100A in stator supply lines. -
