AC amplifiers with ultra-low corner frequency by using bootstrapping
(Institution of Engineering and Technology, 2021)
Artículo / Artikulua,
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 ...
High-linearity tunable low-Gm transconductor based on bootstrapping
(IEEE, 2021)
info:eu-repo/semantics/article,
In this brief, a novel pseudo-differential low-transconductance amplifier is proposed based on the bootstrapping technique. The transconductor is implemented using two voltage follower topologies as amplifiers with their ...
A family of alternating current amplifiers for ultra-low frequency operation
(Wiley, 2021)
Artículo / Artikulua,
A family of capacitively coupled alternating current (AC) amplifiers featuring ultra-low (below 1 Hz) corner frequency is presented. This is achieved by using high-gain devices which actively boost feedback resistance and ...
