BiCMOS simple explanation


INTRODUCTION

In integrated technologies, BiCMOS, also called BiMOS It is the integration of BJT and CMOS technology into a single device.

In the 1990s modern integrated circuit technologies began to make BICMOS a reality.

BICMOS Circuit uses the characteristics of each type of transistor most appropriately.

Generally this means that high current circuit use metal oxide semiconductor field effect transistor (MOSFETs) for efficient control & portion ....etc

The history of semiconductor devices starts in 1930 s when Lienfed and Heil first proposed the mosfet. However it took 30 years before this idea was applied to functioning devices to be used in practical applications, and up to the late 1980 this trend took a turn when MOS technology caught up and there was a cross over between bipolar and MOS share.CMOS was finding more wide spread use due to its low power dissipation, high packing density and simple design, such that by 1990 CMOS covered more than 90% of total MOS scale.

In 1983 bipolar c ....etc

NMOS - N-type metal-oxide-semiconductor logic uses n-type field effect transistors (MOSFETs) to implement logic gates and other digital circuits. These nMOS transistors operate by creating an inversion layer in a p-type transistor body. This inversion layer, called the n-channel, can conduct electrons between n-type source and drain terminals. The n-channel is created by applying voltage to the third terminal, called the gate. Like other MOSFETs, nMOS transistors have four modes of operation: cut-off (or sub-threshold), triode, saturation ....etc

touchless technology full seminar report and abstract

Abstract
It was the touch screens which initially created great furore.Gone are the days when you have to fiddle with the touch screens and end scratching up. Touch screen displays are ubiquitous worldwide.Frequent touching a touchscreen display with a pointing device such as a finger can result in the gradual de-sensitization of the touchscreen to input and can ultimately lead to failure of the touchscreen.

To avoid this a simple user interface for Touchless control of electrically operat ....etc

CMOS circuits utilize complementary MOSFETs, i.e; NMOS and PMOS devices together in various patterns to create functional blocks like AND or OR gates. However the problem with these types of CMOS circuits is that they are inherently low power circuits. They cannot handle large currents. So when your block needs to have a large fan out (need to drive a large no of outputs, i.e; more current required) CMOS circuits fail. That is why we use BiCMOS. They are very similar to CMOS circuits except for the BJT(Bipolar Junction Transistor) output stage. ....etc

ABSTRACT
BiCMOS technology is a combination of Bipolar and CMOS technology. CMOS technology offers less power dissipation, smaller noise margins, and higher packing density. Bipolar technology, on the other hand, ensures high switching and I/O speed and good noise performance. It follows that BiCMOS technology accomplishes both - improved speed over CMOS and lower power dissipation than bipolar technology. The main drawback of BiCMOS technology is the higher costs due to the added process complexity. Impurity profiles have ....etc
