“…The first version of this capsule is powered by a small lithium battery and holds for three days which is the expected stay duration of the capsule inside the body. Figure 1 shows the electronic pill (ePille®) construction [10], this paper focuses on the enhanced modulation of the telemetry unit of this capsule. (1 ) where A c is the carrier amplitude, f c is the carrier frequency, and θ c is the carrier phase.…”

A new approach of continuous phase QPSK BandPass modulation technique is being developed as enhancement to the QPSK modulation scheme for inductive data transmission (NFC). The modulation is based on Gaussian filtering of the phase transition from one state to the other rather than discontinuity in phase shift. The carrier is based on low frequency 115 KHz suitable for human body energy penetration due to its large skin-depth and lower inductive power attenuation. The complete signal processing is done digitally, external coil and capacitor is used for transceiver interface. The telemetry assists a smart pill swallowed by human being to trigger an actuator for drug delivery, record temperature, or perform diagnostic task inside the body. The smart pill includes 32bit processor, 16 Kbyte memory, temperature sensor, telemetry unit, and additional external peripheries. The complete system is designed, embedded in one SoC, and realized on ASIC with chip-area less than 14 mm².

“…The field on/off signal generated by the field detector circuit is used as the reset for all the digital peripherals including the microcontroller. The microcontroller used here is developed by the ASIC design center at Hochschule Offenburg, based on the Von Neumann architecture proposed in [73,74]. Since then, further modifications have been carried out over the years, and the present version has been the one presented in [75].…”

Low power, low cost inductively powered passive biotelemetry system involving fully customized RFID/NFC interface base SoC has gained popularity in the last decades. However, most of the SoCs developed are application specific and lacks either on-chip computational or sensor readout capability. In this paper, we present design details of a programmable passive SoC in compliance with ISO 15693/NFC5 standard for biomedical applications. The integrated system consists of a 32-bit microcontroller, a sensor readout circuit, a 12-bit SAR type ADC, 16 kB RAM, 16 kB ROM and other digital peripherals. The design is implemented in a 0.18 µm CMOS technology and used a die area of 1.52 mm × 3.24 mm. The simulated maximum power consumption of the analog block is 592 µW. The number of external components required by the SoC is limited to an external memory device, sensors, antenna and some passive components. The external memory device contains the application specific firmware. Based on the application, the firmware can be modified accordingly. The SoC design is suitable for medical implants to measure physiological parameters like temperature, pressure or ECG. As an application example, the authors have proposed a bioimplant to measure arterial blood pressure for patients suffering from Peripheral Artery Disease (PAD).
