Abstract
A real-time closed-loop electrical stimulation and recording device includes an electrical stimulator, a processor, two or more sample-and-hold protection circuits, and an analog front-end amplifier. The electrical stimulator is connected to a physiological tissue. The processor controls the protection circuits to sample and hold the first voltage of an analog physiological signal from a physiological tissue before the electrical stimulator generates a stimulation signal. The processor controls the protection circuits to block the analog physiological signal after the protection circuits hold the first voltage. The processor controls the protection circuits to sample and hold the second voltage of the analog physiological signal that replace the first voltage from the physiological tissue after the stimulation signal ends. The amplifier amplifies the first voltage or the second voltage to generate a detection signal and transmit the detection signal to the processor.
