A low-power, BiCMOS front-end amplifier for capacitive detector read-out is discussed. The QDCAL Amplifier is a combination of a Dynamically Controlled Active Load (DCAL) and a Charge (Q) Amplifier. The QDCAL has a gain of 25 mV/fC, a power consumption Pt of ? 1.15 mW (bias circuit not included), an output (0-100%) peaking time t(0-100%) of ? 8 ns at a detector capacitance Cdet = 21 pF, and a mid-band input referred series noise spectral density ?en? and parallel noise spectral density ?in? of ? 1.22 nV/√Hz and ? 1.26 pA/√Hz, respectively. The circuit was developed in the radiation hard SOI BiCMOS-PJFET technology of DMILL.
