A hybrid amplifier topology for low-noise direct-coupled front ends
International Journal of Circuit Theory and Applications, 2023 <p>Hybrid amplifiers combine discrete transistors with operational amplifiers (OAs) achieving superior characteristics compared with commercially available OAs, while keeping simple structures and a reduced number of parts. A single-ended amplifier topology based on a junction field-effect transistor (JFET) is proposed as a means of achieving ...
