9.2.1 Design Requirements

The objective is to design a variable gain, low noise, wideband optical front-end transimpedance amplifier. The design requirements are as follows:

  • Amplifier supply voltage: ± 2.5 V
  • Transimpedance gain: 1 kΩ, 10 kΩ, or 100 kΩ
  • Photodiode capacitance: CAPD = 3.3 pF (additional estimated PCB capacitance = 0.7 pF)
  • Target bandwidth: 130 MHz, 40 MHz, or 14 MHz
