Latest Patents

One of Eric's latest patents is for an Analog FIR Filter. This invention comprises an input terminal for receiving an input signal and a first filtering circuit that includes a first transconductance device. This device is configured to generate a first current signal proportional to the input signal. The first analog switch is commuted by a first digital gate signal and is designed to block the current signal when the first digital gate signal has a first value. It transmits the current signal to a first integrating capacitor when the first digital gate signal has a second value. The innovation is characterized by the first digital gate signal comprising a periodic series of pulses, with widths proportional to the filter coefficients.

Another significant patent is a Method and Device for Reducing Radio Frequency Interference of Proximity and Touch Detection in Mobile Devices. This invention features a proximity sensor with a sensing node that receives a radio frequency signal. The signal is coupled to an intermediate node through a first capacitor and then to a ground node through a second capacitor. An RF amplifier is connected to the sensing node, generating the radio frequency signal, which is transmitted using an antenna. The capacitance of the antenna is measured to determine the proximity of a conductive object, enhancing the functionality of mobile devices.
