This paper describes a novel frequency compensation method for a low dropout regulator (LDO). The proposed load tracking-zero compensation circuit not only eliminates the need for a bulky external off-chip capacitor that is typically employed in conventional compensation techniques, but also consumes very low additional quiescent current of 7.5μA that makes this method highly suitable for integrated...
A 3 channel ECG system with wireless data transmission is presented. It is built as a System in Package (SiP) consisting of 6 dies and 39 SMD components mounted on a FR4 substrate at a size of 2.45 × 2.45 mm2. Design considerations and ASIC partitioning is addressed in this work. In addition, measurement results are presented proving that a SiP can compete with a System on Chip.
A novel adaptable analog/digital converter (ADC) that combines analog/digital conversion and entropy-coding for integrated data compression and low-power operation is reported. The converter has high flexibility of operation in terms of adaptable resolution, conversion rate and input signal statistics. This feature allows to adaptively react to changes of the situation and to put the device in each...
