Ideale Diode Schaltung. An ideal diode also acts as a switch when the diode is forward biased it acts like a closed switch as shown in the figure below. Eine ideale diode mit stromspiegel ist leider auch nur fast ideal.
Die schaltung in bild 4 kommt einer idealen diode sehr nahe. So when positive voltage is applied across the anode to the cathode the diode conducts forward current instantly. Ideale diode mit stromspiegel.
Below is the ltspice simulation of a simple ideal diode mosfet circuit.
The connections of component s end and terminals are polarized. Sie hat in durchlassrichtung eine flussspannung unter 100mv wenn die ausgangsspannung über der schwellenspannung des mosfet liegt. An ideal diode consists of two terminals like a normal diode. To minimize this forward drop you can configure a mosfet as an ideal diode which has a very low drop in the forward direction equal to the current times the mosfet s on resistance while blocking the current in the reverse direction.
