B.7. Collector-Emitter Voltage and Collector Current in the Saturation Region
An equation for VCEsat (VCE in the saturation region) can be obtained using the equations for IB, (B.27) (with leakage components neglected), and IC, (B.23), to eliminate VBE. The approximate equation for IB is again
The equation for IC, (B.23), which neglects the VAF term (well justified at low voltage of the saturation region), and the –1 is
Equation B.33
Eliminating VBE between the approximate form of (B.27) and (B.33) gives
Equation B.34
where
Equation ...
