In Sensor-ASIC circuit design several basic analog functional blocks can be identified, which occur frequently and therefore may be designed for multivalent purposes. This usually refers to structures as time-continuous pre-amplifiers, gain programmable amplifiers in switched-capacitor (SC) technique, filters in SC technique, current sources, programmable bandgap references, and one time programmable (OTP) registers, which store the data for the adjustment of the analog components. The design and some parametric results of those functional blocks will be presented and described, as well as their application in two different Sensor-ASIC's being fabricated in an in-house 5V 1µm CMOS process.
