Paper Title:
Advanced Analog-to-Digital Conversion Using Voltage-to-Frequency Converters for Remote Sensors
  Abstract

This paper presents an advanced analog-to-digital conversion technique based on a voltage-to-frequency-to-digital conversion that is suitable for remote sensors, telemetry applications and multichannel data acquisition systems. A voltage-to-frequency conversion part can be based, for example, on high performance, charge-balance voltage-to-frequency converter (VFC), where monostable is replaced by a bistable, driven by an external clock, or other existing high performance VFCs. The frequency-to-digital converter “bottleneck” problem in such promised ADC scheme was solved due to proposed advanced method of the dependent count for frequency-to-digital conversion. This ADC technique lets receive many advantages such as high accuracy, relatively low power consumption, low cost solution, wide dynamic range, great stability and faster conversion time in comparison with existing VFC-based techniques. The conversion rate (6.25 µs to 6.25 ms) in such ADC scheme is programmable, non-redundant, shorter than for pulse counting technique and comparable with successive-approximation and Σ- ADC.
