This paper presents a SoC (System-on-a-Chip) dedicated for a single-chip smart capsule which can be used to continuously monitor human alimentary canal pH and temperature values. The SoC is composed of the pH and temperature sensor interface circuit, a wireless transceiver, the power management circuit and the flow control logic. Fabricated in 0.18 μm standard CMOS technology, the SoC occupies a die area of ~9 mm 2 . The SoC consumes 6.15 mW from a 3 V power supply, guaranteeing the smartdoi:10.5573/jsts.2016.16.5.542 fatcat:zqmezxz5lfeutp3gl2cy6mg33i
