hello,every one
can anyone tell me how to analyze the "lossy integrator",or recommend relative references.
it consist of an operational amplifier and R//C as the feedback load
thank you
10-bit flash adc
I am glad to exchange idea with you too
can we communicate by email?

flash adc design
Thank you for your answer.
Can you explain the R and C in the following formaluation more clearly.
"sample or conversion time > RC * n * ln2"
and the following are my question of the above formulation
1.how does the formulation being obtained, can you recommend a paper...
hello,everyone
Iam designing a flash adc now.
To generate the reference voltages, a resistive reference ladder has to be used, and my problem is i don't know how to determin the value of the resistence.
Can anyone tell me how to determin the value of the resistence?
can anyone give me the...
calculate snr matlab
hello,everyone
I have completed a flash ADC, and i want to use the matlab to process the data simulated by hspice, so as to get the INL,DNL,SNR,and so on.
but i don't know how to do it, can anyone give me an example or some methods to do this?
best regarads.
hello everyone
i am now reading some thesis on filter
the dynamatic range is mentioned frequencyly,bue i don't know what is the meaning, can anyone explain it
eg: dynamic range(THD<-40dB) 54dB
thank you
hello everyone
i want to do a vga in uwb system, and in many thesis it should contain a dc offset cancellation cell. In most thesis ,it contain OTA+LPF+(V-I converter) and inserted between the output of the whole VGA and the output of the first VGA cell
it's just a sketch map, and i am not clear...
hello,everyone
i am doing a vga simulation in cadence, but i come up against difficulties:
i want to see the waveform about the gain versus the vctrl(the voltage to control the gain )to certify whether they have exponential relation
but i don't know how to do it
a reference told that i can ust...
Thank you for your reply.
My VGA is full differential architecture , and according to you sample ,I write sentence like this:
Vinp 2 0 dc=1.2v ac sin(0 0.5m 100meg)
Vinn 9 0 dc=1.2v ac sin(0 -0.5m 100meg)
Vctrl 4 0 dc=1.3v
And the outputs are connected to node 5 and 11 respectively
(the...
