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).

“…First-order compensation is considered to be a basic approach to implement high-precision BGRs, which, however,can only help to achieve a temperature coefficient between 20 to 100 ppm/°C [1]. To solve this problem, many high order curvature correction techniques have been developed [2,3,4,5,6,7], in which, auxiliary circuits with considerable area must be employed. For optimizing the temperature coefficients of BGRs without auxiliary circuits, different types of resistors are employed which lacks of a full elaboration on the selections of resistors types [8].…”

In this paper, an original method is proposed to implement temperature compensation for a bandgap reference (BGR) circuit without any auxiliary circuits. By employing resistor combinations (formed by different type of resistors) with specified temperature coefficients (TC), the temperature coefficient of a previous reported bandgap reference is improved from 22.11 ppm/°C to 3.499 ppm/°C (−25°C-85°C). In order to accomplish the improvement, a useful model is also proposed to help understand the relationship among the TCs of resistors' combinations and BGR.

“…Many researches have been carried out on high-performance reference circuits with low temperature coefficient (TC) and high PSRR operation [7][8][9][10]. Conventional voltage references are based on bandgap reference (BGR) circuit, which is one of the most fundamental building blocks in integrated circuits [11][12].…”

This paper presents a temperature/supply stable and resistorless voltage reference for high-precision portable electronic products. the reference obtains a good temperature coefficient over a wide temperature range through high-order curvature compensation. In order to reduce the temperature nonlinearity, the piecewise linear temperature curvature compensation circuit is used. The voltage reference is simulated with 55nm CMOS technology. It operates at the voltage of 2.5V and generates a stable voltage at 0.742V with a minimal temperature coefficient of 3.19ppm/℃ for temperature ranging from -40 to 125℃.
