Abstract:
1. A current-to-voltage converter, for receiving an input current, and accordingly generating an output voltage, comprising: a current tracking bias circuit, for generating a first bias according to the input current; a current-to-voltage unit, connected to the current tracking bias circuit, having a plurality of transistors and two current sources, for receiving the input current and the first bias, and generating the output voltage according to the input current, wherein the first bias determines a range of the input current, and the current-to-voltage unit further has a first current control device, and the first current control device changes a current conduction level thereof in response to the first bias, such that a rising or falling speed of the output voltage is enhanced; and a voltage clamp bias circuit, connected to the current-to-voltage unit, for clamping voltage levels of two ends where the voltage clamp bias circuit is connected to the current-to-voltage unit.
