I consider phase compensation of LTC7803.
To calculate the output impedance of the internal EA, the transconductance and EA voltage gain (DCgainea) are required, but the value of the voltage gain is not in the data sheet.
The output impedance of EA is considered to be the following equation.
Roea = DCgainea / GM = DCgainea / 2mmho
What is the value of DCgainea? Or is there any mistake in the above idea?
