Abstract :
A wideband buffer amplifier, suitable for amplifying fast pulses originating from a high-impedance capacitive source (photodiode, transducer, biological probe, etc.) has been designed and fabricated using 3-5/spl mu/m NMOS technology. The circuit exhibits wide bandwidth (4.6 MHz) and fast rise time (100 ns) even for large capacitances (~10 pF) at its input and output terminals. A wide range of input signals (from 5 nA to several hundred mA) can be handled.
