hi all,
i have found that my method "b. Plot id vs vds for variou........" works well, but it requires lots of cal.
the method mentioned by the journal also works well & requires less cal.
i would like to try the gm/Id method if i have free time. anyway, someone has tried these two methods...
Hi,
If you were asked to start a design with a new cmos process technology, e.g. 0.35um cmos technology from some other vendor, how are you going to extract the level 1 parameters in order for you to do the basic calculation? From my point of view, there are two methods.
a. Direct use the...
lm324 amplifier circuit
Hi hi Jepeto,
Refer to your diagram, I agree with you that we should add a virtual ground (for your case, you put in the virtual ground as VREF = 2.5Vdc). However, with this additional VREF, the circuit configuration actually spoiled the main purpose of the circuit to...
Re: This is divide by two?
hi hi,
the simplest u can hv is the below circuit (if u don mind with d glitches)
the above circuit can b implemented using 9 transistors only.
if u need d details, kindly refer to the baker's book.

hippoo
dear all friends,
anybody kindly give me comments regarding my latest two figures, which one is better. kindly give me reasons with your choice.
thank you... :|

Re: Comparator
hi hi,
u may also make use of this folowing diagram:
the software... u may use altera quartus II (free web edition software), u may download the software through the altera website as:

i hope...
hi hi,
beside the TI filter pro, u may refer to the analog devices internet based software:
**broken link removed**
i used TI filter pro and the AD "Interactive Design Tools: OpAmps : Active Filter Synthesis" before, both of them having pro and cont...
i suggest that u use both of them...
i hv try the following circuit practically,
results:
V_AC = 12V
V_DC = -12V
V_BC = 5V
so.... i think the +ve voltage regulator with -ve configuration is working well, rite? (if the node C is going to be the circuit reference node)
with this configuration, of course i will find that my V_2...
dear bimbla,
for your reference, i attach the circuit configuration given by the texas instrument:
i have measured the voltage of V32, it giving me -ve 4.98V (refer to my first circuit diagram)
as per what u hv said that this circuit do not hv the common ground... may i know why it is not...
i use 7805 to build a -5V supply as below:
as the power supply of+12V is floating, will it giving any problems? let's say if it is going to connect to the negative terminal of the op-amp.
if it is going to cause problems, any suggestion to alter the problems or there are some other types of...
