80 M sample/s low powered, high resolution comparator in radiation hard SOI-BiCMOS technology

This comparator is intended to be part of the front-end of a larger read-out chip to be used with particle detectors. Its demands are low power, high speed and a high resolution. The comparator is implemented in a radiation hard 0.8 μm SOI-SIMOX technology and offers us NMOS, PMOS, PJFET and NPN bipolar transistors plus two types of resistor and two types of capacitor. The comparator has a resolution of <500 μV, consumes 360 μW, is clocked at a fixed frequency of 40 MHz and has a sampling rate of 80 M sample/s
