Design Example: Capacitance Multiplier Circuit01:20

Design Example: Capacitance Multiplier Circuit

704
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.

Bus Impedance Matrix

105
Calculating subtransient fault currents for three-phase faults in an N-bus power system involves using the positive-sequence network. When a three-phase short circuit occurs at a specific bus, the analysis uses the superposition method to evaluate two separate circuits.
In the first circuit, all machine voltage sources are short-circuited, leaving only the prefault voltage source at the fault location. The positive-sequence bus impedance matrix can be determined by solving the nodal equations,...

Area of Science:

  • Photonics and Optical Engineering
  • Integrated Optics
  • Optical Communications

Background:

  • Optical interconnects require increased link capacity.
  • Multi-dimensional multiplexing (mode, polarization, wavelength) is key to enhancing capacity.
  • Existing solutions face limitations in flexibility and integration.

Purpose of the Study:

  • To propose and demonstrate a novel 96-channel silicon-based on-chip reconfigurable optical add-drop multiplexer (ROADM).

Main Methods:

  • Design and monolithic integration of a silicon ROADM chip.
  • Incorporation of a six-channel mode/polarization de-multiplexer and multiplexer.
  • Utilizing a 6x16 array of microring-resonator (MRR)-based wavelength-selective switches.

Main Results:

  • The fabricated ROADM chip integrates over 1000 elements, including 96 MRRs.
  • Achieved on-chip excess loss of 5-20 dB, inter-mode crosstalk <-12 dB, and inter-wavelength crosstalk <-24 dB.
  • System experiments with 10-GBaud QPSK signals showed power penalties < 2 dB at a BER of 3.8 x 10^-3.

Conclusions:

  • The demonstrated 96-channel silicon ROADM is a significant advancement for hybrid multiplexing systems.
  • The device offers flexible and efficient add/drop functionality for optical signals.
