Latest Patents

One of Lin's latest innovations is a high power transistor switch with low transmission loss. This transistor switch comprises a first field-effect transistor, a second field-effect transistor, a clamping circuit, and a coupling circuit. The first field-effect transistor is controlled by a first voltage source to be turned on during a transmission mode. The second field-effect transistor, which is controlled by a second voltage source to be turned off during the transmission mode, has one current carrying terminal connected to the first field-effect transistor. The clamping circuit is connected between the gate of the second field-effect transistor and the second voltage source. The coupling circuit is connected between the gate and one current carrying terminal of the second field-effect transistor.

Another notable patent is the high dynamic range optical receiver preamplifier. This device provides a transimpedance feedback path between the output node and the input node, which comprises a feedback resistor and two diodes coupled in opposite directions. When the input current signal is too large and the voltage reaches the diode's threshold voltage, the preamplifier can provide a current path passing the signal to solve the problem of non-uniform charge-discharge time. The two diodes, coupled in opposite directions, allow the photodiode to work under large-signal current conditions, thus increasing the dynamic range of the transimpedance preamplifier.
