Re: Unable to find InstName attribute in LTSpice for mac
Hello, I haben't got an answer from Mike so far. In the meantime you could start with an existing symbol like opamp2 from folder [Opamps]. Open this symbol and then do a "File->Save as" with the new

Re: Need help to design a transimpedance amplifier
Thanks for your swift response.. And whatever the maximum current I can detect upto 5V ...that is fine... But I am worrying about how to choose the suitable opamp and design parameters....and

Well....Bandwidth required is 1 MHz.. APD biasing voltage is 26-30V. Photodiode capacitance is 5pF

Re: Looking for a IDT74CBTLV3253 model.
Modified version of "COUNTER TEST.asc" has been uploaded to Temp, named "COUNTER_TEST_works.asc". I added the parameter needed to make the "counter" logic device actually count. Andy ?

Re: Need help to design a transimpedance amplifier
That is quite easy. There lot of cmos type opamp with low drift spec. You can have t network on feedback which keep cost down for single opamp design. You also need cap on feedback to keep it stable.

Re: Mechanical switch
Hello David, You could make a bouncing switch with a V-source (PWL) as the control voltage for a switch SW. You can see a "typical" bouncing switch on the top-left picture.
