BASIC ELECTRONIC CIRCUITS/19EC203/ E.Divya/ Unit 2/ CE,CB & CC CONFIGURATIONS CE CONFIGURATION In this type of configuration, the current flowing out of the transistor must be equal to the currents flowing into the transistor as the emitter current. emitter is grounded and it is used as the common terminal for both input and output. It is also called as grounded emitter configuration. Base is used as a input terminal whereas collector is the output terminal.

3. Output Characteristics It is defined as the characteristic curve drawn between output voltage to output current whereas input current is constant. To determine output characteristics, the base current IB i s kept constant at zero and collector current Ic is increased from zero by increasing VCE.This is repeated for higher fixed values of IB.

4. The output characteristic has 3 basic regions:
