    Delta Sigma Modulator - Capacitor value

    Thanks for the reference. Unfortunately I don't have that book, but I will see maybe it is available somehow online or in the library. Thanks once again.

    FFT - EZwave Mentor Graphics

    Hi all... I am currently working with EZwave. I have used FFT function to analyze the bitstream output of delta sigma modulator. I used transient analysis (start time: 0, Stop time: 10ms, step: 0.5us). Can someone share about how to use the FFT function correctly in EZwave for the given...

    Delta Sigma Modulator - Capacitor value

    Hi all.. At the moment I am designing a first order delta sigma modulator. I would like to ask you regarding the value of the capacitor and resistor used in the integrator (the circuit used is op-amp with R in inverting input and C in the feedback network). Could someone share about this...

    Tutorial for Mentor Graphics Board Station or Board Architect

    Hai there... Maybe if you have any tutorial for Board station or Board Architect, could you please kindly share it with me? I am currently looking for that but very difficult to find a good one. Thanks in advance for that.

    Electronics project(need ideas)

    Maybe you can try to make a PWM to control a small DC motor. It can be realized with many ways. It is classical circuit and can be found easily how the circuit works. Eventhough it is simple and classical circuit but many improvements can be made so that you can modify it as creative as you can...

    Delta Sigma Modulation SNR - Bit Resolution

    Thanks for your reply. Yes I know about this formula... I have attached a screen shot from the result I got from the FFT calculation from the bit-stream. The clock I used for the DS is 100kHz and the signal input is sinus with f= 1khz. For the FFT calculation I used: Fsampling 200kHz and...

    Delta Sigma Modulation SNR - Bit Resolution

    Hi all... I have problems to determine the SNR and the bit resolution from a Delta Sigma Modulation. I have now a 1st order delta sigma modulation and if I look at the bit-stream at the output of the delta-sigma, I am quite confuse how we can know from this bit-stream the SNR as well as the...
