AC Input Resistance in Common Base Configuration
Ratio of change in emitter base voltage (?VEB) to the resulting change in emitter current (?IE) is called input resistance, i.e., at constant VCB
Value of input resistance Ri in CB configuration is very low. Its value further decreases with increase in collector-base voltage VCB. Typical value of input resistance varies from a few ohms to 100 ohms.
