An analog high-speed wide-range programmable monostable multivibrator

This paper presents a scheme for an analog monolithic monostable multivibrator suitable for use in a wide variety of applications where a need exists for pulses of a known and precise width in response to a trigger signal. The pulse can be programmed either using a reference current or an external capacitor which allow widths from 5 ns to a maximum which is limited only by capacitor values availability. The circuit was fabricated in a standard 1.2 μm BiCMOS technology, but it is shown to be fully CMOS compatible. Measurement results indicate that very high speed is obtained at very low power dissipation and cost
