ABSTRACT
A modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goalis to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Here there is a need to mix the signals of different frequencies or signals of different types, whichemphasizes the use of mixers or multipliers for different RF applications. In this paper, A CMOS analog multiplier, with less number of transistors which can operate at high frequencies with low power and high linearity is proposed. The multiplier works on the basis of parallel connected MOS operation circuit.
