An ECG receiver with a Right-leg drive (RLD) can enable acquisition of a single-lead ECG from a pair of electrodes shared with the Bio-impedance measurement. A PPG signal chain comprises of a current driver for LEDs and a receiver that senses the signal from PDs. The outputs of the three signal chains are digitized by a common ADC and stored in a FIFO which can be read out using an SPI or I2C interface
