A 32-channel front-end circuit for wireless Human Interface Devices (HID) is described. The front-end incorporates a Sigma-Delta ADC combined with an inverse-STF pre-filtering technique to achieve 10.8 ENOB at a conversion rate of 7.5µs per channel. Chopping and digital calibration are employed to achieve an offset voltage < 850µV and gain(More)
Previous research shows that the correlation between income and life satisfaction is small to medium in size. We hypothesized that income may mean different things to people at different ages and, therefore, that the association between income and life satisfaction may vary at different points in the life course. We tested this hypothesis in 3 nationally(More)
