Low-voltage 0.81mW, 1-32 CMOS VGA with 5% bandwidth variations and -38dB DC rejection
(IEEE, 2020)
Artículo / Artikulua,
A CMOS low-voltage amplifier with approximately constant bandwidth and DC rejection is introduced. The design is based on the cascade of a wide linear input range OTA, an op-amp and a servo-loop with extremely large time ...
Gain-boosted super class AB OTAs based on nested local feedback
(IEEE, 2021)
Artículo / Artikulua,
A new approach to design super class AB operational transcon-ductance amplifiers (OTAs) with enhanced large-signal and small-signal performance is presented. It is based on employing two nested positive and negative feedback ...
