WebDec 12, 2024 · Output impedance strongly depends on current through the diode, so the measurement setup should only cause a variation in current that is small relative to average current. ... It would be more accurate to bias the diode with a current source with dynamic output impedance much higher than 100k, for example a Wilson. WebThe input impedance of an electrical network is the measure of the opposition to current (), both static and dynamic (), into the load that is external to the electrical source network. The input admittance (the reciprocal of impedance) is a measure of the load network's propensity to draw current. The source network is the portion of the network that …
