Latest Patents
One of his latest inventions is a gain controller using switched capacitors. This innovative device operates in both sampling and amplifying modes, effectively controlling the gain of an analog input signal. The gain controller comprises an operational amplifier, input capacitors, a feedback capacitor, and switches. The operational amplifier is responsible for controlling the gain of the analog input signal and generating an output signal with the desired gain. The input capacitors are connected in parallel to the input side of the operational amplifier, while the feedback capacitor links the input and output sides. The switches facilitate the connection of at least one input capacitor to either the input signal or a reference voltage, depending on the operation mode and an externally applied digital gain control signal. This design allows for high-speed automatic gain control and reduced power consumption, as the settling time for the gain to reach the desired value is significantly shortened.
