Title: What is the basics of bias voltage for analog design? Post by DP_Design on Dec 16th, 2009, 12:06am You Know who i am to read title, I am very freshman in Analog circuit. So, please give me your generosity... ;D Question: Most of the analog circuit needs some bias voltage. Is there some rule on bias voltage selection? Simply should I do simulation and find the condition or size of transistor for saturation mode by trial and error? Or should I manually calculate all transistor's DC level for saturation and start to satisfy calculation result ? And is there any best way to select proper transistor size? If i choose the bias condition, I can make the circuit in various size and scheme. Then What does make me select the best size of transistor? |
