Two-channel precision converter voltage-to-pulse


Two-channel precision converter voltage-to-pulse

  In this paper for the solution of the transformation "voltage-to-pulse" is proposed implemented in CMOS basis (technical process SGB25VD) structure based on high-frequency converter and comparator multiplexer with symmetrical hysteresis. Increasing the accuracy of the transformation achieved by the proposed method switching input voltages, excluding the through-analog switches. The results of computer simulation confirmed the effectiveness of the developed structure. Practical implementation of an analog-to-digital converter has shown that the proposed method of construction reduces the technological requirements for the components of the system-on-chip and increase its productivity.

Keywords: system-on-chip, analog-to-digital converter, structure, multiplexer, switching, measurement error, comparator, integrator
