Hi,
it is always said that on chip we should try to distribute a current signal of a voltage signal.
As far as I understand, it is mainly because of the accuracy problem. The voltage signal distribution suffers from the voltage drop or inteference on chip.
But if to distribute a current...
circuit design with vhdl
Hello all,
now I want to implement a digital circuit which must realize certain functions, but also not highly complicated function. Finally I want to integrate this digital circuit into the exsiting analog circuit in Cadence.
Therefore, I am wondering I'd better...
convert negative to positive voltage regulator
Dear All,
The normal regulator only converts the positive voltage and their substrate is ground.
Now I want to design a regulator, whose negative input voltage may exceed its negative substrate voltage.
For example, its input voltage is from -10V...
input impedance resonator
If there is a transformer, in the received side, the RLC circuit is composed of the received coil, the capacitor and the load resistor.
If now I want to draw the equivalent circuit of the receiver to calculate its input impedance Rin. Shall I replace the input induced...
Re: only an inductor or LC tank in wireless receiver fronten
Thanks!
Yes, my receiver has a fixed working frequency for implants application
When both of the topologies are possible, could you please explain some details of these design constraints mentioned by you, such like size, cost...
Hallo.
I want to design a wireless receiver for low power applications.
For the front-end, it can be either an inductor to receive the power or a LC tank.
Could someone explain me how to select between these two?
It would be also very nice if you can provide me some literature for reference.
small signal vs large signal
This question has confused me for a long time.
I want to do some theoretical analysis for a CMOS amplifier, just like to derive some formulas of its input impedance, gain .....with Gm, r0 and so on.
But I noticed that normally such kind of analysis with...
an undefined model pnp+cadence
thanks very much, it worked!
But by the way, could you please give me some example of more complicated and accurate model file? or could I find it somewhere in the Internet?
I've just used the simple model file which you wrote. But the circuit I built has...
design bipolar transistors cadence
This sounds very interesting, but I've never done this by myself before.
could you please explain me more details or give me an example, how does a model file look like and how can I attach this self-written model file to cadence?
thanks
cadence schematic pnp beta
I need NPN and PNP to simulate a small circuit in cadence
So I am searching for BJT models for simulation
In analoglib, there are pnp and npn transistors, and I've added them in my schematic and runned simulation. But the simulation was not sussessful and it shows...
calculating input impedance
Now I want to calculate the input impedance of a circuit, the input signal is a current signal, the circuit's input is composed of a complementary PMOS and NMOS common gate amplifier(M1 and M3)
M2, R2 and M4, R4 provide constant voltage bias for M1 and M3
If I want...
a circuit output is going to drive the next stage circuit which is a large capacitive load of the previous stage(please see the simplified picture below)
In order to drive this large capacitive load, should I consider about increasing the current flowing in the previous circuit or should I...
