Abstract
Because the combination of many fields is the trend nowadays, we design a circuit applied for bio-medical sensor to measure health condition of patients instantly. Therefore, the patients will get more comfortable attention by bio-medical SOC chip.e plan to integrate wireless communication, electrical sensor, and software by semiconductor industry and information technology to achieve low-cost, long-tern, small and reliable medical sensors. We design a SOC chip that has the ability of wireless data transmitting and receiving, controllable behavior, and sensing. This SOC includes an ASIC microcontroller, two amplifiers to enlarge different type of signals, a wireless receiver for receiving command, a wireless transmitter for transmitting data, an analog-to-digital converter (ADC) to convert analog signal to digital, two regulators for saving power, and a 4-to-1 multiplex for choosing how many signal passes. All of them are integrated in one single SOC chip. Sensors for detecting biological signal are placed externally.
