The proposed circuits are designed using 65 nm CMOS process technology with a nominal voltage of 2.5 V and a supply voltage of 5 V. The designs are based on stacked low-voltage standard CMOS transistors. The different pre-input stage circuits are compared to each other in terms of their circuit description, drawbacks, advantages and simulation results. The principle of the five designed pre-input stage circuits can be applied to higher voltage range input signals as well.

The proposed HV-driver and level shifter are based on stacked standard CMOS, therefore the design is technology independent. The circuit is designed in 65-nm TSMC technology with a nominal voltage of 2.5 V and optimized for arbitrary supply voltages from 2.6 V to 6.0 V. This range is extended by 41.7% when compared against common drivers and level shifters with the circuit being suitable for a supply voltage range of 2.4 V between 2.6 V and 5.0 V. The total area of the designed level shifter is about 3.8% of that required for similar circuit in previous work.

The sensitivity depends on the geometry and the operating point of the MAGFET. Particular attention is paid to the lateral parasitic conductance between the split drains. The equivalent spectral noise density of the magnetic flux density is measured. Additionally, a macro-model of the MAGFET has been developed for SPICE.

Frontieres CY - Gif-sur-Yvette ER - TY - GEN A1 - Killat, Dirk A1 - Schmitz, Richard T1 - A reflected-light receiver with 2 nA sensitivity using CDS and separate low-pass filtering of the input signal at each clock-phase T2 - Sensors and Actuators N2 - The design of an integrated receiver for reflected light using correlated double sampling (CDS) is presented. CDS has the disadvantage that input signals of high frequencies are folded back to the base band caused by sampling the continuous input signal. However, the circuit presented here uses a new method to limit the bandwidth of the CDS input signal. Two filter-capacitors, one for each clock phase, are periodically connected to the input of the CDS circuit. As the input signal is low-pass filtered by the ohmic output resistance of the optical sensor in conjuction with the filter-capacitors, aliasing can be avoided. Measurements of a test circuit demonstrate the effectiveness of this principle. Y1 - 1996 U6 - https://doi.org/10.1016/0924-4247(96)80145-2 SN - 0924-4247 VL - 52 IS - 1-3 SP - 175 EP - 178 ER -
