Re: Sub circuit heat dissipation not showing
Depend on the definition of 'thing'. For me, 'RMS power' is not a 'thing'. Highland Scots might disagree. With best wishes DESIGN IT IN! OOO ¨C Own Opinions Only <http://www.jmwa.demon.co.uk/>

Re: Need help to design a transimpedance amplifier
Would you like to look at the Idea i posted in the Temp file(photo amplifier 15A) and somebody else reproduced it with different component values(photo amp) i think you may have to rethink your TIA

?I have Windows version 1. Do you think LTspice works with it? Should I blast someone at LTC for daring to come up with a program that doesn't? Does this mean that LTC beats the dust? (or did you

Re: No XP?
Hello, I don't know about whether LTspiceXVII works with Vista, but it may work too. Have you tested LTspiceXVII with Vista? I am sure LTspice will be for free forever. Best regards, Helmut

Thanks John for correcting me. I should have said Average Power.

But whatabout vista? I do not know about you guys, but I hate to putz around with computers. These are just tools, hammers so to speak, and I expect them to behave as such. For your general knowledge

Re: Need help to design a transimpedance amplifier
I read through a few post, you want to detect from 200nA to 100uA with BW>=1MHz. You can do it in one single stage with feedback resistor of 50K. The output range is from 10mV to 5V. This is not hard

Re: RC circuit time delay value not correct
An RC filter does not 'delay' signals, but low pass filters them, with a frequency dependent phase delay. An RC value of 100ps says that the step response gets to 1/e of the final value in 100ps. --

RC circuit time delay value not correct
Hi, i am new to LTSPICE. i am simulating this series RC circuit with an input of 1GHz. sine wave. since the RC value is 100ps. it should introduce a delay of 100 ps to the voltage across the capacitor

Re: Henry's current transformer problem
In another post you said your fundamental frequency is 50 Hz. Are you sure that this ferrite core is suitable for a 50 Hz CT? Normally, low-frequency CTs have nickel-iron cores. With best wishes
