Re: Difference between Active and Passive Devices ?

The Point you explained is one of the criteria of being an active device. For sure Diode is an active device because : 1. Diode being a non linear device has the capablity to highly modulate the current following through it, if we do very small modulation in the voltage applied across it. 2. Special...

Re: What is latchup? Explain the method to prevent it?

Latch-Up is a condition in which the parasitic components give rise to the establishment of low-resistance conducting path between Vdd and Vss with disastrous result. The parasitic NPN and PNP transistors make a SCR structure and if their dc current gain product is greater than 1, then a self-sustai...

Re: Antenna effect in CMOS layout

During the Fabrication Process the large amount of charge is induced in plasma etching, ion implantation and in other processes. If a large interconnect (Poly or other Conducting material) is connected to the Gate of a MOSFET, then this larger conducting material will act as Antenna and will receive...

Re: What is Negative Setup Time and Negative Hold Time Conce

Setup time is the minimum amount of time data must be stable at input before arriving the active edge of the clock. That is to say, if a flip-flop defines a 200 ps data setup time,then the data must arrive 200 ps before active edge of clock arrives. Hold time is the minimum amount of time data must...

About Technology Nodes

We see 90nm, 65nm, 45nm, 32nm, 22nm technology nodes. These technology nodes are decided by dividing the previous node by square root of 2. So that number of components remains the same even after reducing the area by a factor of 2 (because length is divided by square root of 2 so area will be divid...
