sir, i cant understand.... i have done it but still i get negative dB response..........
I have attached OTA design please guide me...... i really need it....
Thanks in advance...
Thanks a lot..........
How to plot the gain plot of OTA in CADENCE spectre? is it frequency Vs. ratio of output current to input voltage? please help me......
After taking dB20 and phase(degree) of this plot can i get gain, phase, pahse margin and gain margin?
please help me i want to find these...
Hello everyone,
I have designed OTA for hearing aid application. I want to measure THD of OTA. How can i measure it?
The value that i get is it in percentage or not?
Another query is that gain of the OTA is the ratio of output current to input voltage or ratio of output voltage to input...
Hello every one,
I have attached design of programmable OTA. but i dont know how to measure parameters like gain, phase, CMRR, PSRR, slew rate etc. To measure all this parameters i have used one test bench which is also attached here.
But problem is that i have measured gain in db, which is...
Hello sir,
Thanks for help
but my design is not based on operational amplifier.
still can i apply the testbench you have suggested for my OTA design?
does it really work?
thanks in advance
Hello everyone
i have generated layout of OTA design shown below. DRC is sucessfully run without ideal_balun
But i dont know how to connect ideal_balun in layout. please help me i got xfmr component error in LVS.
I have removed the ideal balun and put voltage sources with pins connection.
but...
Thanks a lot sir
but i want to apply differential ac inputs to two inputs and input common mode voltage simultaneously than how is it possible? please suggest me how to do?
thanks in advance

How can i solve it? thanks in advance
Thnks sir but I cant understand how to generate test bench for below given OTA design?
which test bench design is suitable for this? i want to find parameters of OTA?
please guide me.
Hello everyone,
I want to find some parameters like gain, bandwidth, unity gain bandwidth, phase, PSRR, CMRR, Slew rate.
is it required test bench for OTA to find parameters?
How to generate the testbench of below given OTA design.
Thanks in advance
I am using CADENCE 6.1.4.
I want to generate layout of programmable OTA design shown in attached file.
How to apply differential inputs so that i can perform post layout simulation
Thanks in advance
How to plot gm Vs vin of OTA circuit?
I have attached OTA circuit.
I want to find gm for whole OTA not for a MOAFET, so plz help me how can i perform this?
I dont know how to make testbench?
hello sir
thanks for your reply
its really helpful for me
but i want to plot Vin Vs gm of programmable OTA. it means of whole circuit not for a particular MOSFET.
plz, help me what to do for it?
Thanks in advance
Hello everyone,
I want to plot transconductance(gm) Vs. Vid curve for OTA. How to draw it plz show me method?
And also tell me how to create emacs file for spectre simulator to perform transconductance measurements?
Thank you in advance.
