## Intrinsic gain of the BJT Solution

STEP 0: Pre-Calculation Summary
Formula Used
output_voltage_gain = Early voltage/Threshold voltage
Avo = VA'/VT
This formula uses 2 Variables
Variables Used
Early voltage - Early voltage is entirely process-technology dependent, with the dimensions of volts per micron.Typically, VA falls in the range of 5 V/μm to 50 V/μm. (Measured in Volt Per Micrometer)
Threshold voltage - Threshold voltage of transistor is the minimum gate to source voltage that is needed to create a conducting path between the source and drain terminals. It is an important factor to maintain power efficiency. (Measured in Volt)
STEP 1: Convert Input(s) to Base Unit
Early voltage: 0.025 Volt Per Micrometer --> 25000 Volt per Meter (Check conversion here)
Threshold voltage: 50 Volt --> 50 Volt No Conversion Required

### Intrinsic gain of the BJT Formula

output_voltage_gain = Early voltage/Threshold voltage
Avo = VA'/VT

## Which transistor has higher gain BJT or MOS and why?

BJT has more gain than MOSFET because MOSFET shows Quadratic I-V characteristics and BJT shows Exponential I-V characteristics and the change in exponential behavior is more as compared to Quadratic behavior.
