An Op-Amp Approach for Bandpass VGAs With Constant Bandwidth
(IEEE (Institute of Electrical and Electronics Engineers), 2018)
Two approaches to implement variable gain amplifiers based on Miller op-amps are discussed. One has true constant bandwidth while the other has essentially reduced bandwidth variations with varying gain. Servo-loops and ...
