Latest Patents

Binkley's latest patents include the "Amplitude-and rise-time-insensitive timing-shaping filters" and the "Remote gain control circuit for photomultiplier tubes." The amplitude- and rise-time-insensitive timing-shaping filter is designed to convert a selected input signal into a bi-polar output signal. This output signal has a zero-crossing point that is independent of the rise-time and amplitude of substantially linear-edge input signals. The filter includes an attenuator for generating an attenuated signal, a delay path for generating a delay signal, and a differencer for subtracting the attenuated signal from the delayed signal. The delay path can utilize various filter configurations to achieve the desired delayed signal.

The remote gain control circuit is designed for remotely controlling the gain of a photomultiplier tube (PMT). This circuit can be used with PMTs that have any selected number of dynodes. It connects to the last dynode nearest the anode in the dynode string, controlling the total dynode supply voltage and influencing the gain of each dynode. The circuit includes an integrated-circuit operational amplifier, a high-voltage transistor, resistors, capacitors, and diodes. Negative feedback is employed to set the last dynode voltage proportional to a voltage controlled by the gain control voltage.
