Over the recent decades, the balance between increasing the complexity of computer chips and simultaneously reducing cost per bit has been accommodated by down-scaling. While extremely successful in the past, this approach now faces grave limitations leadi ...
The state-of-the-art scaled down CMOS processes have led to devices with extremely high Ft reaching several hundreds of GHz. This high F t can be traded with power consumption by moving the operating point towards weak inversion with Ft reaching tens of GH ...

Multi-gate devices e.g. gate-all-around (GAA) Si nanowires and FinFETs are promising can- didates for aggressive CMOS downscaling. Optimum subthreshold slope, immunity against short channel effect and optimized power consumption are the major benefits of s ...
Silicon technology has advanced at exponential rates both in performances and productivity through the past four decades. However the limit of CMOS technology seems to be closer and closer and in the future we might see an increasing number of hybrid appro ...
This paper deals with the development of a four-channel low-power Phased Array Front-End (PhA-FE) at 24 GHz, targeting both low-power radar sensors and battery powered transceiver applications. Typically, PhA-FEs are power hungry architectures due to multi ...

The constant-current (CC) method uses a current criterion to determine the threshold voltage (VTH) of metal-oxide-semiconductor (MOS) field-effect transistors. We show that using the same current criterion in both saturation and linear modes leads to incon ...
Technology scaling improves the energy, performance, and area of the digital circuits. With further scaling into sub-45nm regime, we are moving toward very low supply (VDD) and threshold voltages (VT), smaller VDD/VT ratio, high leakage current, and large ...
The increase of components density in advanced microelectronics is practically dictated by the device size and the achievable pitch between the devices. Scaling down dimensions of devices and progress in the circuit design allowed following Moore's law dur ...
Single-photon avalanche diodes (SPADs) are evaluated in two sub-100nm CMOS technologies. Several geometries are implemented, whereas premature edge breakdown (PEB) prevention is achieved with n-well rings. The octagonal SPADs are implemented in 90nm and 65 ...
