    Opto-isolator/ optocoupler for electric isolation in IC design.

    Hello everyone. I came across while reading the opto-isolator technique used for electric isolation in embedded systems/ Integrated Circuits design that " Opto-isolator is not recommended for electric isolation in power applications IC's mainly due to its dV/dt sensitivity". So I would like to...

    Designing Schmitt trigger oscillator using CMOS NAND gate.

    Hello, I am designing a Schmitt trigger oscillator based on a CMOS NAND gate. The block diagram along with schematics and its results are attached for your reference. I am using the CADENCE tool with 0.35um technology. Question: it can be seen in the result, the charging time of the capacitor...

    Low Pass filter and Schmitt trigger

    Hello I am recovering the PWM message signal at the demodulator side of the system. In the attached schematics you can see Low pass filter which filters high frequency, then the signal is fed to Schmitt trigger to retrieve the message signal. I aimed to design the whole system on IC 350nm...
