Looking at the two elements setting the input impedance, it is not immediately obvious they deliver a 50Ω input match. Looking in towards R g1 , the source will see an impedance >R g1 since the common ...

Get a wideband matched input impedance with ultra-low noise using the active match capability of a new type of amplifier (part 2 of 2) Part one previously published on EDN Abstract: While all fully ...

Assuming that home stereo power output ratings are determined using 6-8 ohm loads, I inspected the back of the box for the sub's input impedance. My eyes widened as I found the answer: 10k ohms!

High input impedance and low noise comes from a carefully-crafted JFET at the input pin, in a circuit that Caldwell cannot reveal. Again in a way that TI is keeping close to its chest, a pair of 100mA ...
