Abstract
A brief review of the existing circuits for input protection of low-current DC amplifiers is followed by a suggestion that GaAsP diodes are suitable for designing protection circuits. Experimental results and the corresponding theory show that these diodes are the best protecting devices applied so far since they are very fast devices and the large energy gap of the GaAsPxP1-x semiconductor ensures extremely low leakage currents.Keywords
