Resonance phase operation of bipolar transistors

This work deals with the amplification scheme of resonance phase operation. For simplicity, the coherent transistor is used for its explanation. It is an ideal transistor model with a transport factor given by /spl alpha/ = exp (-/spl omega//spl tau//sub EC/). The transistor shows periodic resonances In Its current amplification at frequencies f/sub n,curr/ = n//spl tau//sub EC/. Additionally, the output of the transistor is found to operate as a reflection amplifier, where the centres: of the amplification are located close to f/sub n,refl/ = (n-1/4)//spl tau//sub EC/. Prospects of implementation of the new amplification scheme in silicon based bipolar technology are shown by numerical simulation using the 2-D simulator BLAZE from Silvaco.
