Non-zero amplifier time constant can actually increase TIA bandwidth!! must decrease quadratically! If we integrate the output noise, the upper bound isn't too critical. D, n 2 I  4. A: The term “input bias current” (IB) in datasheets – for both op amps and fully differential amplifiers (FDAs) – refers to the DC currents flowing into or out of the amplifier's input pins to create a defined operating point during normal operation, as shown in Figure 1. The function of the photodetector is to detect the incident light signal and convert it into an electrical current; the amplifier converts this current. transimpedance ampli-fiers (TIAs) serve in the front end of optical communication receivers (RXs). Consequently, engineers new to op-amps might overlook this important requirement, which can lead to malfunctioning circuits.
