This is a coninuation of a question I previously asked here.
We made the proto board and it is working in low speeds.The complete circuit is given below.
Let me show the wave-forms at each section of this circuit.
TRANSMITTER:
TIA
You can see from the above images that,the width of the pulse is increased compared to the pulse width of the TX signal.The TX signal pulse width is 21.5uS and at the comparator output the pulse width is 42.5uS.
What my firmware engineer suggest is that if we can make the pulse width of the comparator output also in the range of TX pulse width(21.5uS) is good for the system.
May I know is there any method to adjust the pulse width in this circuit such that the pulse width of RX almost equal to TX(Yellow color,In all waveforms)?
The datasheet of all components is given below.
In all waveforms Yellow is the transmitted signal.Going to the Gate of Mosfet.Respective output at each section are shown in Green
