The discussion revolves around using SIMetrix to verify amplifier circuit calculations The user has calculated various parameters, including gain and output voltage, but is unsure how to utilize SIMetrix for analysis Guidance is provided on setting up the schematic, ensuring proper DC biasing, and performing transient or AC analysis to determine the gain ratio The user seeks clarification
What is the Quiescent Operating Point for FETs? - Physics Forums Hi All, I was learning a lot of how to calculate the Quiescent operating point for FET's But suddenly I got this doubt that if i am operating any transistor (BJT, FET) as a switch then I need not calculate the Q - point Am I correct in this? Only when some AC signal is applied to avoid
ALS logic family circuit calculations - Physics Forums The discussion focuses on calculating parameters for an ALS logic circuit, specifically current IOL, propagation delay, and quiescent power consumption The estimated IOL at gate 1 is calculated to be 0 3mA based on the input currents of subsequent gates
Audio Video The 5532 OpAmplifier - Physics Forums While not exactly a brand-new design, the type (NE)5532 dual operational amplifier (opamp) is a very capable device giving low distortion with good load-driving capabilities, and a remarkably good noise performance It is only quite recently that better opamps for audio work have become available While these can give truly outstanding results, the cheapest of them costs ten times more than
Small signal AC modeling for a boost converter with resistive losses . . . I've attached my attempts at the solution and the actual question below I believe the only issue I am having is I don't know how to get rid of "I" in both my final inductor and capacitor equations as the HW states I shouldn't have anything in term of I I believe I need to put "I" in terms of
