Latest Patents

Chiou's latest patents include a current-switching method and circuit for digital-to-analog converters. This innovative circuit enhances compliance and linearity in the output current characteristic. By incorporating an additional transistor that remains in a permanently-on state at the output port, the circuit increases output impedance. Furthermore, it addresses the issue of simultaneous switching-off of two control transistors by connecting the gate of one transistor to a reference voltage set between the logic-high and logic-low states of the input digital signal. This method meets the requirements of a 3 V working voltage with 1.2 V output compliance and achieves 10 bits of linearity in the output current characteristic.

Another significant patent is a circuit for monitoring battery voltages of telephone terminal facilities. This circuit includes a ringing detection circuit that generates a pulse signal in response to an off-hook or ringing signal. It also features a power detecting circuit that monitors battery voltages and a latch in series with the power detecting circuit to output a signal indicating the status of the detected battery voltages. The edge-triggered design of the power detecting circuit and latch ensures low power consumption and minimal voltage variations during operation.
