    摘要： A method includes providing an active circuit element in a feedback path between an output node and a bypass node of a charge pump of a Phase Locked Loop (PLL). The bypass node is a node to which a charge current or a discharge current is steered to by the charge pump when neither charging the output node nor discharging the output node is required. The method also includes servoing the bypass node to the output node through the active circuit element in the feedback path to maintain a same voltage at the output node and the bypass node when neither the charging of the output node nor the discharging of the output node is required.

    摘要： A dual polarization quadrature modulator includes an input planar lightwave circuit (PLC) configured to deliver coherent light to a polymer-on substrate device including a plurality of electro-optic (E-O) polymer optical modulation waveguides configured to each phase modulate the coherent light, and the E-O polymer optical modulation waveguides output modulated coherent light to an output PLC configured to combine waveguide pairs of phase modulated light into Mach-Zehnder interferometric signals, combine pairs of Mach-Zehnder interferometric signals into quadrature modulated signals. A polarization rotator rotates modulated light from one of the quadrature modulated signals into an orthogonal polarization. The output PLC combines the quadrature-modulated and rotated quadrature modulated light to form a dual polarization, quadrature modulated light signal. The PLCs and the polymer-on-substrate device are integrated onto a single assembly substrate.

    摘要： A current control mechanism for use in low power consumption circuits with limited headroom includes a differential transistor pair from whose collectors a current output is taken. The current output is a function of a reference voltage provided at bases of a reference transistor pair having emitters that are coupled to the bases of the differential pair. The reference voltage is controlled by a pair of control transistors that control current through a load. A pair of tracking transistors can be provided to track supply voltage. A single-ended topology can also be implemented.
