Abstract :
A medical data acquisition system chip has been integrated using a BiMOS (bipolar metal-oxide semiconductor) process. This chip integrates a low-noise bipolar instrumentation amplifier, a programmable switched-capacitor notch filter, an 11-bit ADC (analog-to-digital converter), a 7-bit DAC, and an asynchronous serial interface. Biomedical signals such as ECG (electrocardiogram), EEG (electroencephalogram), invasive blood pressure, temperature, respiration, and cardiac output are picked up by transducers, probes, and electrodes. Typical signal levels are 50 μVp-p for the EEG and 1 mV p-p for the ECG. These low level biological signals are converted into voltages or currents
