Latest Patents

Hightower holds a patent for a "High input impedance buffer with low feedback resistance." This invention is designed for use in instruments that do not require high-frequency compensation or calibration. The patent describes an operational amplifier that receives an input signal through a high resistance input resistor and produces an output signal proportional to the input. The feedback resistor block and feedback attenuator create the feedback path, establishing the buffer gain. The low resistances of these components are significantly less than that of the high resistance input resistor, eliminating the need for compensation and calibration capacitors. Additionally, a switching circuit selects resistors in the feedback resistance block and feedback attenuator to provide predetermined gains for the buffer.
