Hello,
I am using Codewarrior 10.1 on a 64-bit windows 7 machine. I am attempting to program my S08 uC with the PE Micro universal multilink interface (rev C) but the programmer will not recognize that the processor is there.
I am nearly positive that the circuit is correct, I am using the...
I am also playing with the idea of gating the input to the the circuit using a CE amplifier with a PNP load that I can switch. Very crude but almost no cost other than the area, which isn't a big deal at this time.
Need to find a dual op-amp with an enable pin to drive the input of a push-pull driver stage. Don't need high speed, don't need high accuracy, just need low cost i.e. <$0.25/10k. Any suggestions?
That is probably the best place to start this project. The reason we want to eventually move to Cadence and Spectre is because we do our IC design in those tools. That part is more of a long term goal rather than an immediate requirement.
I believe by " concatenate a standard header, your...
Hello,
I am trying to do genetic algorithms research using Matlab and Cadence IC6/Spectre. I will be generating a matrix in Matlab that defines the connections in a circuit. I want to somehow pass this information into Cadence to define the circuit connections, simulate the circuit...
The simple answer is that it is not practical to convert this circuit into a variable supply.
The LM78XX series regulators are fixed output regulators with no externally accessible control loop. You would need to put an adjustable regulator on the output them in order to make a variable supply...
I found when I used that chip that the DO signal gets very noisy, which is what I believe you are describing, when the analog input voltage is very low (< 100mV).
I have recently created a FSK transceiver in hardware using a 555 timer circuit as the modulator and a XR2211 as the demodulator and I am now looking to implement the system using a dsPIC or similar low cost chip. I however do not have much DSP experience.
My problem is that I am currently...
Does anyone know the effects of nickel content in silver nickel relay contents. I know that it provides higher resistance to welding but what are the effects of higher and lower content? If there is a higher than normal content of nickel would this be bad?
Any information will be helpful
My coworker was able to work something up for a d flip flop:
*SRC=74HC74
*SYM=74HC74
.SUBCKT 74HC74 1 2 3 4 5 6 7 14
*1=CLR 2=D 3=CLK 4=SET 5=Q 6=Q\ 7=GND 14=VCC
* 20=Momentary Clock 21=Q before RC 22=Q after RC 23=VCC that we can look
R1 14 23 1
R2 14 20 1
R3 21 22 1
C1 3 20 0.0000001 IC=0
C2...
We're using Altium Designer here, so all we have is the standard spice. We don't really care how generic or specific the model is, we just want something so we can confirm basic circuit functionality.
Does anyone have a simple spice model for a D flip flop? Our simulator doesn't have any special spice libraries to work with so we need a primitive model. Just looking for basic functionality, don't really care about slew, drive strength, metastability, or any of that.
