Preamplifier system with selectable input impedance |
摘要 |
Systems and methods are provided for selecting an input impedance of a preamplifier device. Multiple feedback paths are provided to an amplifier device of the preamplifier. The feedback paths are selectable to switch feedback paths in and out to configure the preamplifier to the desired input impedance. The desired input impedance is selected to match the input impedance of the input signal system to optimize the performance of the preamplifier.
