Paper Abstract

In this work we present experimental results of silicon-only bipolar phototransistors fabricated in a 0.35μm commercial BiCMOS technology without process modifications. The transistors are characterized over a wide optical spectral range at 410nm, 675nm, 785nm, and 850nm, providing significantly improved -3dB bandwidths up to 390MHz @ 410nm light and responsivities of 1.76A/W @ 675nm corresponding to quantum efficiencies of 359% normalized in terms of the quantum efficiency of a silicon photodiode.
