Example text

Figure 11: Chopping, phase 1; input offset voltage is + Vos Figure 12: Chopping, phase 2; input offset voltage is - Vos Sinee the input offset is +Vos on phase 1 and -Vos on phase 2, ehopping introduees a square wave with amplitude 2Vos peak-to-peak at the input. This square wave is then amplified by the amplifier. Another way to deseribe this effeet is that the ±1 multiplieation is a modulation proeess. The DC offset and 1/f noise from anormal amplifier (shown in Figure 13) is modulated only onee (by the output multiplier), so the offset and l/f noise is modulated from DC to the ehopping frequeney (see Figure 14).

If the data rate is sufficiently low, the two interfaces can be merged. , analyte-Ioaded air for gas sensors). , to avoid outgassing). This increases the cost of 10 connections compared with standard products and, therefore, the number of lOs must be minimized. A review of microsensor packaging can be found in [14]. • Suppression of noise and crosstalk in the analog frontend: The combination of analog and digital circuitry as well as a large number of simultaneously active sensors lead to crosstalk and large substrate noise.

In [28], Yang et al. developed a modified conversion algorithm (novel ramp generator) that also eliminates the need for a latch inside the cell. lm2) [30] have been presented for applications in which the area is less critical. The use of cell-Ievel ADCs allows data to be processed already in the sensor array. This reduces the amount of data that has to be transmitted off-chip and can eliminate the need for additional data-processing hardware. X, a) x, X. Xc X.
