In this research five current conveyor types are presented in order to deeply understand DVCC. Besides, DVCC supports differential input systems which increase the immunity to noise, resulting in improved received signal. However, Current mode Differential Voltage Current Conveyor (DVCC) was able to redress this drawback by its ability to provide constant bandwidth for different gains. simple circuit deigns schemes but it can’t handle high frequency communication applications. Most analog systems are implemented using operational amplifier. The development in CMOS technology serves widely in this direction. Thus, the manufacturers are going forward to meet the mentioned specifications by developing efficient device architecture. Most common communication devices are small but have high quality of services and low power consumption to protect user’s health. To provide some background, Section II presents general expressions of the linearity metrics of a single-stage system as a function of DC parameters. The goal of this work is to characterize quantitatively the linearity of sub-micron CMOS devices using widelyknown metrics such as 1dB compression and 3rd-orderintermodulation intercept points. However, the equally important issue of linearity is not well studied. As CMOS technology scales into the sub-micron regime, issues such as excess thermal noise due to hot electron e#ects have been well documented #2#. Introduction R ADIO frequency designs in CMOS are increasingly being explored to take advantage of rapid technology advances. In particular, the linearity of short-channel MOSFETs is examined. These two #gures of merit measure the linearity of a system. Specialty radio receiver ICs are also commonly available.This paper presents analytical expressions for the 1dB compression and third-order intercept points as a function of DC-bias and technology parameters. Radio receiver ICs are also characterized by low current consumption, which helps to keep power dissipation in the tuner within an acceptable range. Radio frequency (RF) automatic gain control (AGC) is programmable in steps of one or two decibels (dB). For gain and offset compensation, an integral digital-analog-converter (DAC) may be used. Some radio receiver ICs use AM up-conversion and FM down-conversion as a type of filter. Radio receiver ICs that use BiCMOS II technology are also available. Another logic family, complementary metal-oxide semiconductor (CMOS), uses a combination of p-type and n-type metal-oxide-semiconductor field effect transistors (MOSFETs) to implement logic gates and other digital circuits. Transistor-transistor logic (TTL) and related technologies such as Fairchild advanced Schottky TTL (FAST) use transistors as digital switches.

Choices include bipolar CMOS (BiCMOS), a silicon-germanium technology that combines the high speed of bipolar TTL with the low power consumption of CMOS. Radio receiver ICs differ in terms of product specifications such as logic family. Radio receiver ICs for specific applications such as television, shortwave radio, and communications are also available. These devices use amplitude modulation (AM), a technique that causes the baseband signal to vary the amplitude or height of the carrier wave to create the desired information content.

AM radio receiver ICs are also available. FM devices use frequency modulation (FM), a technique that causes the instantaneous frequency of a sine-wave carrier to depart from the center frequency by an amount proportional to the instantaneous value of the modulating signal. There are many different types of radio receiver ICs. These radio waves represent a distinct part of the electromagnetic spectrum. In electronics, a receiver is a device that converts radio waves into intelligible sounds or other perceptible signals. Radio receiver ICs are relatively small, but are functionally similar to traditional radio receivers. These integrated circuits (ICs) are designed to receive radio signals for processing and subsequent conversion into a form useful to listeners. Radio receiver ICs support worldwide radio band requirements, including frequency modulation (FM), FM radio data system (RDS), amplitude modulation (AM), long wave (LW), short wave (SW), and weather bands.
