(ABSTRACT) Analogcircuit/IC design for high speed optical fiber communication is a fairly new research area in Dr. Ha's group. In the first project sponsored by ETRI (Electronics and Telecommunication Research Institute) we started to design the building blocks of receiver for next generation 400 Gb/s optical fiber communication. In this thesis research a(More)
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(More)
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(More)
This paper present a differential architecture of cmos transimpedance amplifier is offered to obtained the input capacitive load in-sensitive and the very minimum noise structure. The suggested TIA is dependent on the differential structure and composed of a regulated cascode block and a differential amplifier along with active feedback. To increase the(More)
