Hbt amplifier
Webthree types of Class-C amplifier demonstrated with an HBT of eight emitter fingers, each finger 2-µm wide and 20-µm long. The HBT is self biased with a 50-Ω resistor R1 between the base and emitter. In addition, in the Type-B and Type-C amplifiers, the based-emitter junction is shunted by a single-finger HBT of 2 µm × 20 µm.
