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 ...

Biasing CMOS amplifiers using MOS transistors in subthreshold region
(2004)
The implementation of large-valued floating resistive elements using MOS transistors in subthreshold region is addressed. The application of these elements to bias wideband AC coupled amplifiers is discussed. Simple schemes ...
