Abstract |
In this paper, Variable gain amplifier (VGA) has been designed using the gain compensation technique on H- SPICE platform using 180nm Predictive Technology Model (PTM). VGA with the larger bandwidth, along with lower power consumption, dynamic variable gain has been designed. The feedback and feed forward bank of resistors have been implemented in order to compensate for the gain. For the better performance and to increase the common mode rejection ratio, the common mode feedback technique is used. The gain varies from -1 to 40dB with 0.5dB gain steps with bandwidth of 1MHz and the power consumption is 1.98mW. | |||||||||
