Title
On Frequency Response And Stability Of An Optical Front-End With Variable-Gain Current Amplifier Using A Bipolar Junction Transistor Translinear Loop
Abstract
A comparative analysis of implementations of an optical front-end with variable transimpedance intended for optical storage systems in two different BiCMOS technologies is given in this article. The variable-gain current amplifier within the optical front-end is designed by using a modified balanced type of the bipolar junction transistors translinear loop. The predictions of the optical front-end mathematical models are confirmed by the measured results. They show that a 0.6-mu m BiCMOS silicon technology implementation with worse bipolar junction transistor parameters (unity-gain frequency, current gain , and the Early voltage) gives much better stability than a 0.35-mu m BiCMOS silicon-germanium technology implementation. As a consequence, the useful measured transimpedance dynamic range of the proposed optical front-end is 17.5 times larger in the 0.6-mu m BiCMOS silicon technology than that in the 0.35-mu m BiCMOS silicon-germanium technology.
