Ultra-low-power temperature/voltage monitor in tsmc 40nm IP

CSEM has developed a low-cost, ultra-low-power 60 GHz MIMO FMCW PHY that can be integrated into radar-on-chips with custom digital processing for specific applications.
This solution leverages CSEM’s decades of experience in ultra-low-power RF CMOS system-on-chip design.

The icyTRX ultra-low-power RF transceiver is designed to meet standards such as Bluetooth Low Energy (BLE), 802.15.4 PHY Layer (e.g. ZigBee), and proprietary standards with data rates from 62.5 kBit/s up to 4 Mbit/s.
icyTRX offers 5.3 mW consumption in receive mode from a 1.0 V supply. icyTRX is a complete transceiver that is designed for miniaturization, yielding an area of analog RF of less than 1 mm2 in 55 nm CMOS, requiring minimal external components thanks to high degree of integration. icyTRX is designed for easy integration into ASICs and SoCs.

The icyflex-V processor is a new ultra-low-power core based on the RISC-V 32-bit ISA, compatible with off-the-shelf open-source and/or proprietary programming tools.
This new development represents a cost effective yet performing alternative to proprietary cores for next-generation ultra-low-power system-on-chip developments.
The core was optimized for performance, code density and power consumption and delivers up to 3.2 CoreMark/MHz while consuming as low as 14 uA/MHz in TSMC 55 nm low-power process.

The IP consists of a Successive Approximation Register (SAR) architecture ADC using charge-redistribution technique.
The ADC IP is configurable regarding resolution (6-13 bit) and sample rate (up to 10kS/s) and power consumption down to 1.9 µW. The input voltage range is quasi-rail-to-rail guaranteeing more than + 1.7 V@ 1.8V power supply.
An optional calibration technique can be applied to compensate degraded mismatch behavior of technology capacitors.
