High-speed interface circuit for differential capacitance transducers
A high-speed capacitance difference-to-sum ratio measurement circuit is presented for differential capacitance transducers. It consists of a switched-capacitor input stage, two sample-and-hold (S/H) circuits followed by voltage-to-current (V/I) converters, and a current-ratio-controlled relaxation oscillator. This circuit offers a square-wave output whose oscillation period is directly proporti...
متن کاملSwitched capacitor triple slope capacitance to digital converter
A high accuracy switched capacitor, triple slope digital converter suitable for differential capacitive sensors is presented. The proposed technique accepts differential capacitive sensors possessing either linear or inverse characteristics and provides a linear capacitance to digital conversion. The output is dependent only on a pair of d.c. reference voltages and the clock frequency. Detailed...
متن کاملVery low-voltage fully differential amplifier for switched-capacitor applications
A fully differential opamp suitable for very-low voltage switched-capacitor circuits in standard CMOS technologies is introduced. The proposed two stage opamp needs a simple low voltage CMFB switched-capacitor circuit only for the second stage. Due to the reduced supply voltage, the CMFB circuit is implemented using bootstrapped switches. Minor modifications allow to use chopper stabilization f...
متن کاملA Fully Differential Switched Capacitor Amplifier Modelling and Parameter Evaluation
This paper develops an analytical model for a standard topology, fully differential, switched capacitor amplifier; including the base amplifier offset voltage and common mode range, and capacitor mismatch effects. The amplifier is designed in a 0.6 μm process and the analytical model accuracy is compared with the simulation results.
