    Series of Parallel Packs Battery Cells Balancing

    Ok, of course voltage is the same. But according to simulations SoCs are not. This is exactly the problem I have to solve. Here's a picture of the simulated SoCs of 48 cells. The battery is taken from this article. I have run the same simulations performed here: "Lithium-ion Battery...

    Series of Parallel Packs Battery Cells Balancing

    Hello, I have to simulate a BMS of a Li-Ion Battery. It is formed by 8 packs, each made by 6 cells connected in parallel, all connected in series. I've read something about balancing techniques, but all references i've found explain how to balance single cells connected in series, as parallel...

    Switched capacitors Gm-C Low pass filter

    My delta is 0.279%. If I try to reduce it by a factor 10 or 100, the cut-off does not scale accordingly.

    Switched capacitors Gm-C Low pass filter

    Hi, I have to design a Gm-C switched capacitor filter according to the technique used in this article. Simulations of cut-off vs duty cycle are good, but i do not understand why the cut-off seems a nonlinear function of duty cycle for small delta. Thank you for reply Lorenzo Manoni

    [Moved]: Sub_Hz lpf filter time response

    Hello, I have to design a sub hz low pass filter according to the technique used in this article: https://ieeexplore.ieee.org/document/5930351/ I'm simulating it in Cadence. The frequency response is good and the cut-off is at 68 mHz. I tried to simulate the transient response to an EEG...

    EEG-signal-processing-analog circuit

    Re: Eeg signal processing analog circuit OK. Anyway if one wants to test the circuit with ideal Eeg signal without noise, is there the possibiity to do that?

    Subthreshold biasing circuit

    Hello, I have to design a biasing circuit for a Trasconductance amplifier operating in weak inversion region with a 1.25 V supply. I am using Cadence. I've seen that the Threshold voltage depends slowly (tens of mV) by the dimensions of the transistors. This causes large variations of the...
