Abstract :
A monolithic charge-to-amplitude converter integrated circuit (QAC IC) was developed with a bipolar application-specific integrated circuit (ASIC) technology. The QAC IC could be used as a building block of a wide-dynamic-range analog-to-digital converter (ADC). Stacking more than two QAC ICs, one could achieve larger dynamic range than that of the single QAC. The QAC IC could be used in a narrow gate application as well as in a wide gate application. The QAC IC was examined in terms of input impedance, transfer function of the current signal, and linearity. The input impedance was kept 50 Ω up to 100 MHz. The integral nonlinearity was 0.1% for the maximum input charge of 600 pC. The dynamic range of the single QAC IC was 4000 pC
