1 V CMOS subthreshold log domain PDM
(Springer, 2003)
A new CMOS circuit strategy for very low-voltage Pulse-Duration Modulators (PDM) is proposed. Optimization of voltage supply scaling below the sum of threshold voltages is based on Instantaneous Log Companding processing ...

An Experimentally-Validated Verilog-A SPAD Model Extracted from TCAD Simulation
(Institute of Electrical and Electronics Engineers, 2018)
Single-photon avalanche diodes (SPAD) are photodetectors with exceptional characteristics. This paper proposes a new approach to model them in Verilog-A HDL with the help of a powerful tool: TCAD simulation. Besides, to ...

Characterization-Based Modeling of Retriggering and Afterpulsing for Passively Quenched CMOS SPADs
(Institute of Electrical and Electronics Engineers, 2019)
The current trend in the design of systems based on CMOS SPADs is to adopt smaller technological nodes, allowing the co-integration of additional electronics for the implementation of complex digital systems on chip. Due ...

Low-voltage CMOS log-companding techniques for audio applications
(Springer, 2004)
This paper presents a collection of novel current-mode circuit techniques for the integration of very low-voltage (down to 1 V) low-power (few hundreds of μA) complete SoCs in CMOS technologies. The new design proposal is ...

Characterization of electrical crosstalk in 4T-APS arrays using TCAD simulations
(Institute of Electrical and Electronics Engineers, 2017)
TCAD simulations have been conducted on a CMOS image sensor in order to characterize the electrical component of the crosstalk between pixels through the study of the electric field distribution. The image sensor consists ...

Multirate cascaded discrete-time low-pass ΔΣ modulator for GSM/Bluetooth/UMTS
(Institute of Electrical and Electronics Engineers, 2010)
This paper shows that multirate processing in a cascaded discrete-time ΔΣ modulator allows to reduce the power consumption by up to 35%. Multirate processing is possible in a discrete-time ΔΣ modulator by its adaptibility ...
