A 100 Gb/s CMOS transimpedance amplifier (TIA) for high speed optical communication receivers is presented in this paper. The TIA is based on a differential architecture and composed of a regulated cascode block and a differential amplifier with active feedback. It adopts peaking inductors and a capacitive degeneration scheme to increase the bandwidth. The TIA is designed and laid out in CMOS 65 nm...
This paper proposes a control system to widen the bandwidth of piezoelectric transducers (PZTs) for vibration energy harvesting while extracting near maximum power. A straightforward complex conjugate match achieves maximum power transfer only at a single frequency while requiring an impractically large inductance. The proposed system intends to address the problem. It incorporates a bi-directional...
