Hi,
In auCdl netlist generation, I want to generate the netlist shown below
XI1 net16 gnd! / rnpoly2 rl=20 rw=2
.SUBCKT rnpoly2 MINUS PLUS rl=2 rw=2
RR0 PLUS MINUS 190*rl/(rw-6.2e-3) $[NS] $W=rw $L=rl
.ENDS
But the generated CDL out file (File->Export->CDL) is
XI1 net16 gnd! / rnpoly2 M=1...
Hello,
Would you suggest how to use .meas to get the max. Gm of a MOSFET in Hspice when sweeping Vgs value at a fixed Vds voltage?
Also, after getting this max. Gm, could you suggest how to get its corresponding Ids value and the slope of Ids at the max. Gm value in Hspice?
Thank you in advance
Thanks so much for all replies.
I am just a beginner of RF circuits. The target spec. (27MHz/49MHz) is recommended by other. I have no idea about it but am interested very much to know more and don't know how to reverse engineering. Since most transistor type walkie-talkie does not provide the...
Hello,
I am looking for the walkie talkie transceiver integrated circuit design but could not find it. Does anyone please help to provide some reference materials?
Someone told me that the principle of walkie talkie is from super-regenerative principle. Several papers from JSSC discuss this...

The loop gain is not zero. A good reference can be found from P.Gray textbook.
The input-to-output connection is implicit on your opamp system (especially transistor level).
The two poles are usually located at (1) at the connection between the output of 1st stage and input of 2nd stage, (2) at...

I used this book,....just a reference

Re: CMFB partition?
yes I agree with you that CMFB should generally response faster than differential loop. Otherwise the common mode of the signal would fluctuate.
If two transistors is responsible for CMFB, then you have 2 degree of flexibilities to adjust your common mode voltage. It depends...
Re: Parasitic Capacitance
You can try to put your inductor in the impedance measurement machine to plot the equivalent impedance and you will observe the parasitic effect of your inductor
