A CAM is an analog signal processing function abstracted in software accessed by an icon

A large library of standard function CAMs is included

A circuit is implemented simply by selecting, configuring, and wiring CAMs in the design space

Each CAM has a user interface to configure options and limits

Each CAM has an accurate functional model for use with the internal SPICE simulator

Anadigm on a circuit board with clock, power supplies, connectors and input & output buffers.

Serial port connection to AnadigmDesigner2

Accepts differential or single-ended inputs with selectable input impedances

Input and output signals are referenced to GND.

Stores downloads from AD2 in the on-board EEPROM for the “run from EEPROM” mode (don’t need to own a separate PROM burner)

Exercise: Exercise: Build a Circuit that Filters and Rectifies a SignalBuild a Circuit that Filters and Rectifies a Signal

Circuit will take a square wave input and output a bandpass filtered version of the signal and then a rectified version of the filtered signal

This is a basic circuit that will show: The frequency components of the square wave The average DC value of the extracted component

Step 1: Set up a Biquadratic Band Pass Filter Step 1: Set up a Biquadratic Band Pass Filter

Open AnadigmDesigner2. Click on the green box to pop up the CAM selection

window

Step 2: Place Biquadratic Filter in Chip Work SpaceStep 2: Place Biquadratic Filter in Chip Work Space

Choose (double Click) from the list of CAMs a

“FilterBiquad” Filter. (this is a two pole pole Filter)

and set the dialog parameters as shown on

the next page

Step 3: Set Biquadratic CAM parametersStep 3: Set Biquadratic CAM parameters

Step 1: set the Clock to 2000 kHz by moving the spinners

Step 2: Select Band pass filter by clicking on the band pass

radio buttonStep 3: Set Corner Frequency to 5 KHz, gain to 1.0 and Q to

15

Step 4: Click on OK to accept parameters

Step 4: Place a “RectifierFilter” CAM in the Work Space Step 4: Place a “RectifierFilter” CAM in the Work Space

Choose (double Click) from the list of CAMs a “RectifierFilter” CAM. This is a rectifier with a combined single pole

low pass filter.

The combination of the filter and rectifier uses the same number of op

amps as a rectifier alone eliminating the need for a separate

filter.

Please set parameters as shown on the next

page

Step 5: Set parameters for the “RectifierFilter”Step 5: Set parameters for the “RectifierFilter”

Step 1: set the Clock to 2000 kHz by moving the spinners

Step 2: Choose a non inverting Full wave rectifier.

Note the other choices for future reference

Step 3: Set Corner frequency to 100 KHz and gain to 1.

Why 100 KHz? It lets through almost all the energy from the

square wave, but blocks higher harmonics that may alias back

Step 4: Click on OK to accept parameters

Step 6: Add an External Signal GeneratorStep 6: Add an External Signal Generator

Add a signal Generator by clicking on the sine wave on the tool bar and then

place the signal generator here

Next….

Double click on the signal generator to pop up the

configuration window on the next page

Step 7: Configure signal generatorStep 7: Configure signal generator

And set Parameters as shown to create a 5Khz

square wave

Next….wire the circuit up

Step 8: Wire up the circuitStep 8: Wire up the circuit

Wire it up!

1) Just drag the mouse over to the contact or wire that you want to

wire up

2) A wire tool graphic will appear and the contact

will high light

3) Next, click the left mouse button

Next….. Place oscilloscope probes

Step 9: Place Oscilloscope ProbesStep 9: Place Oscilloscope Probes

Place Probes

1) Depress the probe tool icon on the tool

bar (to the right of the sine wave)

2) Drag it near a contact and when the contact high lights, depress

the left mouse button

3) Maintain the probe colors as shown in

the picture so you can follow along

Configure the Simulator

Step 10: Configure the Circuit SimulatorStep 10: Configure the Circuit Simulator

Configure the simulator

• Click on the ‘Simulate’ tab on the tool bar

and then choose the selection ‘Setup

Simulation’

• Configure the options as shown

Next…..

Run the simulator

Step 11: Run the SimulatorStep 11: Run the SimulatorDepress the “Sim” icon to run.

Set time parameters as shown (in red).

• Extracted Fundamental of Square Wave

• Rectified Fundamental

• Input Square Wave 5Khz

Continuing the Exercises: Continuing the Exercises:

Change to a bandstop filter to block rather than pass the fundamental frequency

Simulate to see what a square wave looks like with its first harmonic blocked!

Obtain average DC value of the rectified signal

Exercise: Set Biquadratic CAM parametersExercise: Set Biquadratic CAM parameters

Step 1: set the Clock to 2000 kHz by moving the spinners (it

should already be like this)

Step 2: Select Band stop filter by clicking on the band pass radio button. This will block

rather than pass the fundamental 5Khz signal

Step 3: Set Corner Frequency to 5 KHz, DC gain to 1.0 and Q

to 15 and HF Gain to 1

Step 4: Click on OK to accept parameters

Results: Run the Simulator AgainResults: Run the Simulator Again

• Square Wave with Fundamental Blocked

• Rectified Version

• Input Square Wave 5Khz
