Programmable gain amplifiers our programmable gain amplifier pga portfolio includes low cost general purpose pgas for cost sensitive applications. The gain of an operational amplifier is usually set using two external resistors. This circuit provides a programmable gain function using a quad spst switch and a resistor programmable instrumen tation amplifier.
In this paper the design of variable gain amplifier vga for wireless receiver applications is presented.
Gains up to 1000v v and bandwidths to 4 5ghz get the right gain at the right time. 1 op amp buffer is required to preserve good gain accuracy see text. This is achieved by implementing a programmable gain amplifier circuit. In this paper the design of variable gain amplifier vga for wireless receiver applications is presented.
