In this state of operation, the transistor does not “amplify” the input voltage (V IN) in any way. To use a transistor as a switch, all you have to do is increase the current at the base terminal to a certain level, and the transistor will go into a state commonly known as “saturation.”.

LAMBDA is a measure of the output conductance in saturation. When this parameter is specified, the MOSFET has a finite but constant output conductance in saturation. If LAMBDA is not input, the Level 1 model assumes zero output conductance. Level 1 Model Equations The Level 1 model ...If the voltage divider was 'stiffer' and held the Base voltage constant despite the increased Base current then the transistor would go into hard saturation, with the Base supplying enough Emitter current to keep V E close to 2V even if the Collector current dropped to zero.

With time, the open circuit voltage will probably negotiate to between 3.70V and 3.90V/cell. Remember that a Li-ion battery which has acquired a completely saturated charge keeps the voltage higher for a extended than one which hasn't attained a saturation charge.That means there will always be a voltage drop across the transistor. Taking the typical forward voltage of 1.7V for a red LED, a 5V supply, and a 75 ohm resistor, I get a current of 44 mA.

With only 1.2 mA collector current, you can easily run it well into saturation. 200 mV is a typical value of saturation voltage in a case like that. Even if it is as high as 500 mV, you can easily design for that just be lowering the resistor values.In order to have your drain source current relatively independent of Drain-Source Voltage while operating in sub-threshold region, you should aim for a VDS of greater than approximately 100 mV or 4•k•T/q.
