The performance requirements of transimpedance amplifiers (TIAs) vary significantly between applications. In high-speed communications, wide bandwidth is important, creating challenges in designing for high stability. In most applications, noise performance is critical to overall system sensitivity, and gain requirements vary. 

Large-area photodiodes present higher input capacitance, which may require the design of compensation circuits, and environmental considerations include the ability to maintain acceptable performance over a wide range of temperatures. Size, power consumption, and cost are other ever-present issues. Part 1 considers TIA performance priorities and tradeoffs for two of the three applications discussed in the series: laser rangefinders and LiDAR systems.
