The silicon lateral trench detector in multi-Gb/s receiver systems

Using a simple model based on a parallel plate approximation it is shown, as expected, that a PIN base receiver can outperform an LTD analog but that the advantages of monolithic integration can in many cases make up for that difference. For bandwidths in excess of 3GHz the cost advantages of a monolithic silicon technology might still make the LTD the detector of choice in many applications especially for short haul high speed links for computer interconnects.
