“…This block can be employed in instrumentation and measurement systems involving frequency conversion [39], [40], phase-locked loops (PLLs), frequency-locked loops (FLLs) [39], [41]- [44], clock buffers [45], and ring oscillators [34], [36], [46]. For the implementation of an FVC block, there are mainly two approaches, including counter-based circuits [34], [40] and integrator-based circuits [41], [42], [47].…”

This paper presents an interface circuit for capacitive and inductive MEMS biosensors using an oscillator and a charge pump based frequency-to-voltage converter. Frequency modulation using a differential crossed coupled oscillator is adopted to sense capacitive and inductive changes. The frequency-to-voltage converter is designed with a negative feedback system and external controlling parameters to adjust the sensitivity, dynamic range, and nominal point for the measurement. The sensitivity of the frequency-to-voltage converter is from 13.28 to 35.96 mV/MHz depending on external voltage and charging current. The sensitivity ranges of the capacitive and inductive interface circuit are 17.08 to 54.4 mV/pF and 32.11 to 82.88 mV/mH, respectively. A capacitive MEMS based pH sensor is also connected with the interface circuit to measure the high acidic gastric acid throughout the digestive tract. The sensitivity for pH from 1 to 3 is 191.4 mV/pH with 550 μV(pp) noise. The readout circuit is designed and fabricated using the UMC 0.18 μm CMOS technology. It occupies an area of 0.18 mm (2) and consumes 11.8 mW.

“…Lin and Hou [1] employed current conveyors, up-down counter and ultra-high speed D/A converter to achieve fast FVC. Djemousai et al [2] proposed a FVC circuit which was composed of two equal capacitors, a current source, a set of transistors that act as switches and a logic controller block.…”

“…While there are multiple ways of converting frequency to voltage, 2 of the most important ones are: counter-based and integrator-based converters [2]. The method based on counters uses synchronous digital circuitry with a very high speed clock to count the number of clock cycles that elapse within one period of the measured signal.…”

This paper proposes a high-speed integrating frequency-to-voltage converter. It overcomes the deficiencies of previous converters by removing 2 of their main bottlenecks: event sequencing using pulses and the use of full-swing signals. By using a single-phase algorithm and circuit-level improvements, a frequency-to-voltage converter can operate up to 5 GHz and is ableto discriminate between signals whose periods differ by as little as 0.5ps.
