Abstract :
A simple circuit is proposed for amplifiers that consist of cascaded negative-conductance stages. A biasing scheme is proposed that utilizes the incremental resistance of the active devices to reduce series resistance in the bias circuit. An experimental two-stage tunnel-diode amplifier of this design provides voltage gain of 10 dB ± 1 dB over a frequency range extending from below 200 Hz to above 25 MHz. The proposed circuit appears practical for design of monolithic circuits requiring broadband gain extending to gigahertz frequencies.
