Differential Amplifier using Transistors

Lakshmisree Gopal — Sun, 24 Jul 2016 17:20:40 +0000

As the name indicates Differential Amplifier is a dc-coupled amplifier that amplifies the difference between two input signals. It is the building block of analog integrated circuits and operational amplifiers (op-amp). One of the important feature of differential amplifier is that it tends to reject or nullify the part of input signals which is common to both inputs. […]

Monostable Multivibrator using Transistors

Ligo George — Sun, 16 Aug 2015 14:33:13 +0000

Multivibrator is a non linear oscillator or function generator which can generate square, rectangular and pulse waves. Monostable Multivibrator or One-Shot Multivibrator has only one stable state. By default monostable multivibrator will be in its stable state, but when triggered it will switch to unstable state (quasi-stable state) for a time period determined by the RC time constant […]

Astable Multivibrator using Transistors

Ligo George — Tue, 27 Nov 2012 06:01:14 +0000

An Astable Multivibrator or a Free Running Multivibrator is the multivibrator which has no stable states. Its output oscillates continuously between its two unstable states without the aid of external triggering. The time period of each states are determined by Resistor Capacitor ( RC ) time constant. Astable Multivibrator using Transistors – Circuit In the […]

Single Atom Transistor

Ligo George — Fri, 24 Feb 2012 15:38:53 +0000

Australian and American physicists had developed a Single Atom Transistor, composed of an atom of phosphorous-31 isotope. They had demonstrated a working transistor composed of a single atom, which is about 100 times smaller than the 22 nanometer cutting edge transistor fabricated by Intel. This will be big strike towards the next generation computing. The researchers’s uses […]

Carbon Nanotube Transistors to Break 10nm Level

Ligo George — Sun, 12 Feb 2012 12:13:36 +0000

It is extremely challenging to scale bulk silicon transistors, when the lengths are close to 15nm. 3D Transistor design and Silicon-On-Insulator (SOI) devices are getting more attention to improve the scalability of silicon technology. Carbon Nanotube Transistors have been treated as a possible replacement for silicon transistors, but the question is that, ‘Can CNT transistors can offer better performance over silicon at […]
