Vlsi Approach for Four Quadrant Analog Multiplier for 2.4 Ghz to 2.5 Ghz
Wireless communication world is revolutionized because of the design of the multiplier in the 2.4–2.5 GHz band because of the unlicensed use of the frequency band to the entire user. Multiplier is a key block of analog communication system. Multiplier mixes the signals of different frequencies or signals of different types, to strength signal for long distance communication, which emphasises the designing of more efficient and low power mixers or multipliers for RF applications. MOS RF (radio frequency) multiplier with reduces on chip area operate at ISM Band frequency with high linearity. A 2.4–2.50 GHz band (ISM BAND) multiplier designed and simulated on tanner tool 13. The simulations results presented here are for 1–10 GHz. The circuit is implemented using 180 nm level 3 models and simulated in TSPICE simulator. The transistor operating in linear region reduces the drain current and also the power consumption with large input range. Power consumption is reduces to 68.57 μW.
