Abstract

Variable gain amplifier (VGA) is the key element for amplifying process in analog to digital converter (ADC). In this paper, a low voltage and wide bandwidth class AB VGA is designed using CEDEC 0.18-μm CMOS process for high speed applications. The result show that, the designed VGA has a wide bandwidth of 100-MHz and consumes power less than 125uW at 1V supply voltage. From the results it is also evident that the circuit is capable of working with high linearity and wide bandwidth. The frequency response (Gain) and the wide bandwidth of this class AB VGA is better than previously reported class AB VGA. Smaller transistors are used to make the chip small and it occupies only 0.003 µm2. Such a VGA is suitable for high-performance RF devices.
