Latest Patents
Shiwei Wang holds a patent for a sensor readout circuitry, which includes a biopotential signal sensor and a neural probe. The patent describes a method for the readout of an analog sensor input signal. The circuitry comprises a delta-sigma modulator and an input stage designed to receive an analog sensor input signal. This innovative design incorporates a transconductance amplifier and a current mirror that utilizes a flipped voltage follower. The feedback signal from a digital-to-analog converter of the delta-sigma modulator is processed to perform subtraction between the analog sensor input signal and the feedback signal. This process is executed in the transconductance amplifier and mirrored by the current mirror to produce an output from the input stage. The transconductance amplifier features a series of choppers that form a chopping loop, ensuring that the analog sensor input signal remains in baseband at the node where the feedback signal is received.
