摘要:
An Injector Junction Field Effect Transistor (IJFET) is disclosed which, in addition to having two gates (G1, G2) a drain (D) and a source (S), also has an injector (I). The device may be used as a high impedance charge or current amplifier in, for example, an x-ray flourescence device. On applying current to the injector, carriers are introduced into the channel of the device, allowing a small gate leakage current to flow to restore charge to the input. A small restore current is therefore controllable by low impedance injector circuits.
