Low power HF Microelectronics : A unified approach The book is organised in four parts with generous contributions covering: (i) process TCAD technology; (ii) device modelling characterisation and circuit simulation; (iii) reliability and testability; (iv) analog and digital circuit and system design. In modern low power HF microelectronics the interaction needed between these parts to achieve the desired system performances means that frequently there will be an alliance and or overlap among them. It is fundamental to high yield successful manufacturing to relate in a quantitative manner the sensitivity of the electrical performance of the final devices and or circuits to variations in structural parameters doping profiles layout thermal effects and design
