Alfred Nordmannis theory. A methodology for the filter design yielding practical design equations is explained. A topology for the loop filters is proposed: they are Gm-C filters. The specifications of the various building block are discussed. Considerable attention is given to non-idealities such as circuit noise

C offset and flicker noise as well as eliminating the gain mismatch in the I and Q signal paths are presented..By minimizing the quantization noise at an intermediate frequency, bandpass Delta-Sigma converters offer the most efficient method of analog-to-digital conversion of the IF signal. Moreover

Heinrich Hertz and the Berlin School of Physicsysics exams under Hermann Helmholtz with flying colours and taken a position as assistant to his famous teacher. His enthusiastic statement about Berlin not only concerns his special and very successful situation at the time; above all, it reflects the fact that Berlin had developed into a leading i

Heinrich Hertz and the Geometrisation of Mechanicsl content was characterized by the assumption that neither force nor potential energy are fundamental quantities of mechanics. When a mechanical system seems to be acted on by forces, it is, according to Hertz, because it is rigidly connected to another system of hidden masses whose fast cyclic moti
