Designation of a negative clamping circuit. please help.

I am clamping the negative peak of the signal to a specific level without attempting to change the amplitude of the signal. In order to clamp...

I2C signls

I2C bus line drivers are designed as what is called "open collector" or "open drain" which means that the driver only has a provision to turn...

Designation of a negative clamping circuit. please help.

Designation of a negative clamping circuit. please help.

Cucumber: Your clamping circuit can be built using a concept as I'll describe. You'll select a capacitor to AC couple your 20V to -15V signal @...

USB to RJ45

This extension scheme is bogus and violates the cable length of USB. Just because the OP has changed the cable type and connectors does not legitimize...

6-Input CMOS NOR Gate

The standard gate devices are designed according to the logic function desired. So it is not the gate that is "naturally" inverting. If one goes to...

IR Switching.

Also consider that if you put a small MCU behind the IR receiver it can do the decoding in FW and then drive the output to...

I2C signls

No you do not require I[sup]2[/sup]C between the comparator output and the MCU. Just connect the outputs right to port pins of your MCU that your...

6-Input CMOS NOR Gate

voltage amplification

Note that the single transistor common emitter amplifier circuit inverts the signal.

voltage amplification

Acting as a voltage amplifier it will be easy to analyze this by considering to put resistor in the collector to V++ supply connection. Put another...
