摘要： A wide input range amplifier includes a first and second stage. The first stage has first and second inputs, first and second outputs, and first, second and third voltage sources. The first stage accepts input signals having a first common mode voltage range and outputs a first output signal having a second common mode voltage range and being amplified a first amount. The second stage has first and second inputs connected to the first and second outputs of the first stage, respectively. The second stage accepts input signals having a common mode voltage in the second range and outputs a second output signal having a third common mode voltage range and being amplified a second amount.

摘要： A differential driver includes a switching module and first and second voltage controlled voltage sources. The switching module has a plurality of switches each controlled by an input signal, a first voltage input and a second voltage input, and a signal output. The first voltage controlled voltage source is connected to the first voltage input. The first voltage controlled voltage source has a low impedance. The second voltage controlled voltage source is connected to the second voltage input. The second voltage controlled voltage source also has a low impedance. The switching circuit outputs an output signal having an output voltage and current controlled by the first and second voltage controlled voltage sources. The output signal is based upon the input signal.
