Developed for recharging small nickel-cadmium batteries used in handheld FM transceivers. Field-effect transistors serve as constant-current sources when gate is shorted to source. Practically any N-channel JFET having drain-to-source cument of 8-15 mA will work. FETs shown were measured individually and grouped to give desired choice of 15- or 50-mA charging currents.-G. K Shubert, FET-Controlled Charger for Small Nicad Batteries, Ham Radio, Aug. 1975, p 46-47.
