“…The thickness of electrically insulating adhesive material may affect overall electrical properties of the design. However, with the use of an adhesive thinner than Si chip and lens, this affect can be made insignificant [58]. This is validated by using a 5 µm thick adhesive in [58] and less than 10 µm in [19], which has minimized this affect.…”

“…Furthermore, LIA's gain is directly proportional to the lens size [19], [58]. As an added benefit, LIA also provides reasonably high bandwidth [58]. In general, on-chip LIA provides high efficiency-bandwidth product compared to other such methods [19].…”
