i wonder how to get the gm for large signal, i try to run dc analysis ,but the result is not satisfied, i don't know how to measure the output current(if full-differential), should i connect a resistor or a voltage source for the load in my output ports?
the gm for the small signal, how to get...
i try to complete the dc analysis as you told,but i wonder:
vid is a dc signal or a sine wave?
how to get the output current? connect a resistor or a voltage source?
how to use the calculator to get the deriv Iout/Vin?
dear sir:
recently I have learned to design a gm-c filter, i wonder how to simulate the transconducor in cadence, will you please teach me the necessary simulation, someone told me to complete the dc sweep to get the linerity, but how to do it?
what do i need to complete the...
1)First, you have to check the op. point. Nothing strange, just the usual operation. Be sure that the biasing condition are good for your architecture. Then put a Vdc source connected to the output with value Vdd/2. It will be necessary later. Some current will flows in the output source (offset...
thank you for your reply
what do you mean about the transistor level?
i used nmos and pmos in my circuit, now someone advise me to simulate in pspice,but i don't know how to simulate the transconductor which used in gm-c filter.
dear all：
recently I try to simulate the schematic of transconductor in SpectraRF in cadence，the transconductor will be applied into anti-aliasing filter which is made of the architecture of Gm-c.
I come up with the problem for the firse time, when the circuit is defined, I have tried to...
