    Closed: Sigma Delta ADC Noise Floor

    I have a DT DSM with 3rd order loop filter with CIFF architecture. In Si, the low frequency noise floor is seen to increase from the idlechannel noise floor when some input sinusoid is applied to the...
  2. Closed: [moved] Distribution of process and mismatch in ADE XL monte carlo analysis

    In ADE XL monte carlo analysis the process and mismatch have gaussian distribution by default. Is there any option through which we can change the distribution (like e.g. uniform for process and...
  3. Closed: Re: PSRR Comparison between Fully Differential and Pseudo Differential Topology

    I know that writing KCL and KVL will give the answer (possibly true for most of the circuit questions) and I know the answer too. What I wanted is an intuitive explanation.
  4. Closed: PSRR Comparison between Fully Differential and Pseudo Differential Topology

    Is PSRR better in Fully Differential Circuit as compared to Pseudo Differential Circuit? If yes,why? Please post answers with clear explanations...
  5. Closed: Re: [Moved]: spectre stb analysis of an autozero amplifier

    The problem is that the low frequency pole due to 'gmin' should ideally come at gmin/Caz but simulation result shows little higher pole frequency. As I reduced gmin from 1e-12 to 1e-20, the pole...

  7. Closed: Re: [Moved]: spectre stb analysis of an autozero amplifier

    Actually with gmin=1e-12 and autozero cap Caz=1pF, the pole should be at (1/2*pi) Hz, whereas in loop gain plot, the pole comes at about 30Hz. If I reduce gmin down to 10^-20, the pole moves down to...
  8. Closed: [Moved]: spectre stb analysis of an autozero amplifier

    I have an amplifier with autozero implemented. The overall amplifier is implemented as a switched capacitor amplifier. In the amplification phase, if I break the loop (put 'diffstbprobe' or...
