7.2.1.1 Design Requirements

The objective is to design a low-noise, wideband output transimpedance amplifier. The design requirements are as follows:

  • Amplifier supply voltage: 3.3 V
  • Transimpedance gain: 40 kΩ
  • Photodiode capacitance: CPD = 1 pF
  • Target bandwidth: 240 MHz
  • Integrated input-referred noise: 50 nARMS (noise bandwidth = 250 MHz)
