have anyone done any simulation of the DSM . here is my design.. but my output seems to be inverted.. anyone know if im doing anything wrong or can explain to me why my waveform is inverted.
my output bit steam when input at Vmax there should be more 1s at the top however my waveform stated otherwise.
thanks for the prompt reply. but when i design my functional block design using matlab-simulink i dont need to invert my signal after the integrator. i've tried inserting an inverter after my integrator but it doesnt work. i can only invert my Q or use Q bar for as my output. But i still dont understand why my analog simulation is inverted when my integrator suppose to be taking the difference of the analog input and the feedback.
