Could you explain why this is the case?

Hello there. I am stuck trying to figure out the voltage gain of a cascode amplifier from a small signal analysis. The circuit seems to be under-determined for reasons I do not understand or maybe I am missing the perfectly obvious. Here's my small signal model: The only relation I can...

Hello there. I am taking a closer look at the small-signal behavior of a common source amplifier with active load (see image) and I wonder which capacitances cause the decrease in gain for high frequencies (beyond 106 Hz). I do not know about the magnitudes of the input and output capacitances...

Ah okay, thanks a lot. To put it in in simple words: the load is in fact a load, but with respect to the NMOS current source.

Hi there. Could somebody please explain to me why this circuit is referred to as 'common source amplifier with active load'? From my understanding a load would be something external that is attached between the output and the ground terminals. For example a resistor attached to a voltage source...

Hi, I am working on a little electronics project where I need to convert 15V DC to 5V DC. I was hinted at the LM2576 (datasheet) because it is easy to use and has a built in current limit which is just what I need. The functional block diagram (p12) has a nice display of the internals of the...
