SUMMARY
The forum discussion focuses on solving for the resistances RD, RS1, and RS2 in a self-bias transistor circuit. The user successfully calculated RD to be 2000 ohms using the voltage gain equation AVNL = -mg(RD//rd) with a given value of -8 for AVNL. However, the user encountered difficulties in determining RS1 and RS2, as the voltage gain is only accurately approximated as (-gm RD) when there is no un-bypassed source resistance (RS1). The discussion emphasizes the importance of understanding Vgs (quiescent) and Vds (quiescent) to derive the total source resistance and voltage gain expressions necessary for solving RS1.
