Modeling N-well
Hi all,
I was wondering how to best model a N-well in a substrate model. Is a diode model sufficient? If so, should the size simply reflect the total surface area? Any papers or documents about this would be appreciated. Thanks.
So after the state 1010, the next rising clock will change q0 to 1 which subsequently changes q1 to 0. At this point, the output is 1001. When this happens, your NAND gate will set the output to 1110, as you had expected. The problem is that this means that q2 and q3 both see a rising edge...
Is this possible?
the parallel method is for signals at much higher frequencies. you can probably just solder a simple R and C at one end for a simple RC filter. or if you need more selectivity, then insert a generic IC filter.
There is a free MATLAB toolbox for delta-sigma design. After you install the toolkit, you can use the function calculateSNR to find your SNR of your frequency spectrum.

Corners are the extreme conditions for which the design must still meet the design specifications. For example, you may design a circuit with a power supply of 2.5 V, but the circuit should still work for values a little bit above and a little bit below.
rms voltage is found by multiplying the peak value by 0.707 (approx for 1/sqrt(2)).
KWH cannot be found with simply V and I. A KWH is found by multiplying watts by the time the device is in use.
See link for def of apparent power.

Cadence has a built-in SPICE reader. If you are using the Analog Environment, simply go to Setup-Environment and set the SPICE Netlist Reader option to yes. If you are using the command line, refer to the spectre user's guide. Hope that helps.
Vswitch in Hspice???
You need to specify a voltage value greater than zero for vs. Otherwise, you will not have any current flowing through the switch and the voltage at node 2 will not change.
