Three-phase controlled rectifiers and inverters, matrix cycloconverters, and cascaded power stages typically comprise large numbers of power transistors, each with its own driver circuit...

Comparator uses signal-dependent hysteresis
Comparator uses signal-dependent hysteresis
03.29.2022 Circuits

Sometimes, you need to distinguish between two voltages, using some hysteresis in the decision. When the levels of the compared signals vary over a wide range (for example, a few orders of magnitude), the hysteresis width should vary similarly...

Improved amplifier drives differential-input ADCs
Improved amplifier drives differential-input ADCs
03.28.2022 Articles

ADCs with differential inputs are becoming increasingly popular. This popularity isn't surprising, because differential inputs in the ADC offer several advantages: good common-mode noise rejection, a doubling of the available dynamic range...
