Design Example: Capacitance Multiplier Circuit

1.6K
In integrated circuit technology, a capacitance multiplier is often utilized to produce a larger capacitance value when a small physical capacitance falls short. This is achieved by a circuit that multiplies capacitance values by a factor of up to 1000, such that a 10-pF capacitor can replicate the performance of a 100-nF capacitor.
The circuit illustrated in Figure 1 below incorporates two op-amps, with the first operating as a voltage follower and the second acting as an inverting amplifier.

Area of Science:

  • Photonics
  • Optical Sensing
  • Materials Science

Background:

  • Fiber Bragg Grating (FBG) sensors are widely used for various measurements.
  • Current multiplexing techniques for FBG sensors face limitations in system capacity.
  • Spectral overlapping of FBG sensors is a significant challenge in dense sensor networks.

Purpose of the Study:

  • To develop a novel encoding strategy for FBG sensors to increase multiplexing capacity.
  • To demonstrate a method for uniquely identifying multiple FBG sensors under spectral overlapping.
  • To enhance the number of sensors handleable within a single optical channel.

Main Methods:

  • An encoding strategy using two binary codewords for amplitude and phase patterns was designed.
  • Specialized FBG sensors were manufactured based on the developed encoding strategy.
  • A theoretical framework and experimental setup for interrogating the central wavelengths of encoded FBG sensors were developed.

Main Results:

  • A proof-of-concept with three uniquely identifiable FBG sensors under spectral overlapping was successfully demonstrated.
  • The proposed method achieved a three-time improvement in system capacity, effectively increasing the number of multiplexed sensors.
  • The assessment of overlapping errors indicated a high precision of approximately 3 pm, suitable for practical applications.

Conclusions:

  • The developed encoding strategy significantly enhances the multiplexing capability of FBG sensors.
  • The unique amplitude and phase patterns allow for reliable identification of sensors even with overlapping spectra.
  • This approach offers a practical and effective solution for increasing sensor density in FBG-based measurement systems.
