AC amplifiers with ultra‐low corner frequency by using bootstrapping [PDF]
Electronics Letters, 2021 A novel architecture for an AC (i.e. high‐pass) amplifier is proposed allowing a drastic reduction of the cutoff frequency to the sub‐Hertz range. It builds upon the classic AC configuration with a high gain amplifier and a parallel RC circuit in the ...
