Design Example: Capacitance Multiplier Circuit

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:

    • Optical networking
    • Data center interconnects
    • Photonics

    Background:

    • Growing demand for flexibility and capacity in optical networks, particularly for ultra-large data centers.
    • Limitations of traditional reconfigurable optical add/drop multiplexer (ROADM) devices in handling multiple dimensions simultaneously.

    Purpose of the Study:

    • To propose and demonstrate a versatile multi-channel ROADM.
    • To enable simultaneous reconfiguration of both mode and wavelength dimensions through a single add/drop port.

    Main Methods:

    • Utilizing a crossbar optical switching network for the ROADM architecture.
    • Designing the ROADM for compatibility with both wavelength-division multiplexing (WDM) and mode-division multiplexing (MDM) systems.
    • Fabricating and testing the proposed ROADM device.

    Main Results:

    • Demonstrated simultaneous reconfiguration of mode and wavelength dimensions.
    • Achieved insertion loss below 7.0 dB (including mode coupling and crossing losses).
    • Maintained crosstalk below -13.4 dB.
    • Showcased the capability of add/drop ports to concurrently download multiple data signals in a bus waveform.

    Conclusions:

    • The proposed ROADM offers a versatile solution for future optical networks.
    • The device supports simultaneous WDM and MDM reconfiguration, enhancing flexibility.
    • Potential applications in ultra-high-capacity data centers are highlighted.
