BALANCED DIFFERENTIAL TRANSIMPEDANCE AMPLIFIER WITH SINGLE ENDED INPUT AND BALANCING METHOD

A balanced differential transimpedance amplifier with a single-ended input operational over a wide variation in the dynamic range of input signals. A threshold circuit is employed to either or a combination of (1) generate a varying decision threshold to ensure a proper slicing over a wide range of input current signal levels; and (2) generate a bias current and voltage applied to an input of a transimpedance stage to cancel out a dependence of the transimpedance stage voltage input on input current signal levels. 在输入信号的动态范围的宽变化上可工作的具有单端输入的平衡差分跨阻放大器。采用阈值电路以实现以下中的项或组合：(1)生成变化的决策阈值来确保在输入电流信号电平的宽范围上的正确划分；以及(2)生成施加到跨阻级的输入的偏置电流和电压以消除跨阻级电压输入对输入电流信号电平的依赖。
