WebJun 24, 2024 · 1 Answer Sorted by: 1 The current equation you show is the source current: i s = g m v 1 + v o − v s r d s And i s = v s R S So you have: (1) v s R s = g m v 1 + v o − v s r d s It's hard for me to follow what you did but you could use the equation that includes the current through R d. That is, (2) v o R d + g m v 1 + v o − v s r d s = 0 ct rules of evidence objections
