The importance of a transimpedance amplifier in an optical transceiver is very well known. In this paper, a novel CMOS design of the bulk-driven transimpedance amplifier (BD-TIA) is given where the bridge-shunt peaking-based frequency compensation technique is exploited to improve frequency response. A pre-existing active inductor has been used for the same. The electrical characteristics and functioning of this inductor simulator make it a suitable alternative to both floating and grounded spiral inductors. In order to verify the workability of the proposed circuit, it has been simulated with TSMC CMOS 0.18[Formula: see text][Formula: see text]m process parameters. The proposed circuit is useful in low-voltage low-power VLSI applications as it uses a single supply of 0.75[Formula: see text]V. The power consumption of BD-TIA is very low, being 0.37[Formula: see text]mW, because a standard MOSFET has been replaced by a bulk-driven MOSFET (BDMOS), while the 3-dB bandwidth is observed to be 4.5[Formula: see text]GHz. The mathematical investigation and small signal analysis show that the simulation results are in good agreement.

 The development of educational kit must be compiled on how to prepare undergraduate students in the engineering field in following the new trends globally and becoming an alternative to the technical education system based on practical approach. The primary motivation for this research is to design and implement the visible light communications (VLC) educational toolkit, especially in the analog front-end part. It consisted of six kits (transimpedance amplifier, pre-amplifier, DC-offset remover, analog filter, and AGC) in which each kit has one practicum task. There are six tasks and one task for the project by integrating these kits. The undergraduate students can use this educational kit to investigate the physical layer in a VLC system. It provides a low-complexity educational kit, so this is becoming an alternative as supplement course offered in this field. Then, it has a simple design and user-friendly. The development of educational kit must be compiled on how to prepare undergraduate students in the engineering field in following the new trends globally and becoming an alternative to the technical education system based on practical approach.
