Abstract

This paper deals with a novel DC-coupled, large bandwidth, fully differential amplifier dedicated to industrial applications. A family of integrated fully differential amplifiers has been developed in a 1.2 μm, 6 GHz f_T, BiCMOS technology. The stability/gain compromise is improved thanks to on-chip feedback resistors, whereas the gain is doubled by means of connecting directly on chip both of these amplifiers. Measurements on a “cascade” show a 44 dB gain versus a 300 MHz -3 dB bandwidth (that means literally a 47 GHz gain bandwidth product)
