Hi folks,
Currently I use four identical bias ckts to generate currents for 4 different channels. To save the layout area, I can use only one bias circuit to bias 4 groups.
I cannot use simple current mirror to do this because of noise issues.
Can anyone here recommend a bias ckt?
BTW, I...
actually, I meant current driving capability. same approach?
you should know the frequency. different frequency means different drive capability.
for example, a inverter can drive more load in lower frequency.
you can simulate the delay of inverter under different load to analyze the drive...
Hi folks,
I have a question about the bandwidth of opamp used in a basic sample and hold circuit (which includes a switch, a capacitor and an opamp buffer). if the operating frequency of the switch is 1MHz, then what is the requirement for opamp bandwidth or unity gain bandwidth?
bandwidth...
