7.4 Robust digital design in organic electronics by dual-Gate technology
A comprehensive study of dual-gate organic thin-film transistors targeting more robust organic circuitry is performed by Holst Centre, imec and TNO researchers. The difference between zero-Vgs-load and diode-load logic is studied and an optimized design for both is presented. This new design is used in 99-stage ring oscillators, to determine stage delays, and in 64b RFID transponder chips yielding data rates of 4.3kb/s.

7.8 Design issues and considerations for low-cost 3D TSV IC technology
Imec researchers investigated key design issues of a low-cost 3D Cu-TSV technology: impact of TSV on MOS devices and interconnect, reliability, thermal hot spots, ESD, signal integrity and impact on circuit performance. The experimental verification of their importance is presented and changes in current design practices to enable low-cost systems are proposed.
11.5 A 2.4GHz/915MHz 51¥ìW wake-up receiver with offset and noise suppression
Imec and Holst Centre present an envelope detector-based wake-up receiver front-end. A double-sampling technique is implemented to suppress the 1/f noise and DC offset, resulting in a lower output noise level and therefore a better SNR for a given input level. The receiver consumes 51¥ìW and occupies 0.36mm2 in 90nm CMOS. For 10kb/s OOK reception it achieves -69dBm and -80dBm sensitivity at 2.4GHz and 915MHz respectively.

16.3 A 2.6mW 6b 2.2GS/s 4-times interleaved fully dynamic pipelined ADC in 40nm digital CMOS
Imec researchers present a 2.2GS/s 4x-interleaved 6b ADC in 40nm digital CMOS. Each ADC slice consists of a 1b folding stage followed by a pipelined binary-search sub-ADC using dynamic nonlinear amplifiers for low power consumption and high speed. Threshold calibration corrects for amplifier and comparator imperfections and 31.6dB SNDR is achieved with 2GHz ERBW for 2.6mW power consumption.
21.6 A 30fJ/conversion-step 8b 0-to-10MS/s asynchronous SAR ADC in 90nm CMOS
An 8b SAR ADC is presented by imec and Holst Centre researchers. The 90nm CMOS prototype achieves an ENOB of 7.8b at a sampling frequency of 10.24MS/s. The use of asynchronous dynamic CMOS logic, custom designed capacitors, an internal common-mode shift and low-leakage design techniques results in a power consumption of 69¥ìW from a 1V supply. The corresponding FoM equals 30fJ/Conversion-step and is maintained down to 10kS/s.
