Latest Patents

Feng-Cheng Chang's latest patents include a test system, transmitter, and receiver capable of executing multiple tests based on DC coupling configuration. This innovative test system comprises a transmitter, a receiver, a measuring circuit, and a control circuit. The transmitter is coupled to the receiver in a DC coupling manner and includes a signal input circuit that determines an output signal based on an input signal. Additionally, a current source is configured to determine the total current passing through the signal input circuit under non-open/short-circuited conditions. The receiver features an impedance circuit and a coupling circuit that connects the impedance circuit with a high power-supply terminal. The measuring circuit is responsible for measuring the target current/voltage between the high and low power-supply terminals to generate a measurement result. The control circuit then determines whether the transmitter/receiver is open or short-circuited based on this measurement result.

Another of his recent patents is a test system, transmitting device, and receiving device capable of performing multiple tests in AC coupling mode. This system includes a transmitter, capacitor, and receiver. The transmitter features an output circuit coupled to the receiver via the capacitor and a transmitting circuit that sends a predetermined signal to a pad of the output circuit during a first test. A signal generator outputs first and second signals to the pad during different processes of a second test. The receiver includes an input circuit coupled to the transmitter via the capacitor and a switch that operates in different modes during the tests.
