This paper presents a CMOS reconfigurable translinear cell intended to be part of a field programmable analog array. The cell is composed of a recently developed wide dynamic range translinear element and programmable current sources, current mirrors and capacitors. An FPAA built with this cell is able to implement the most common primitives of translinear(More)
This paper reports mixed-signal front-end architecture for z-axis capacitive inertial surface-micromachined MEMS accelerometer. The method consists in capacitance to frequency to digital conversion with the aid of relaxation oscillator and high-precision digital frequency demodulator based on counters for coarse measurement and tapped delay line for fine(More)
This paper reports a mixed-signal architecture for capacitive accelerometers conditioning based on capacitance ratio to frequency conversion and high-precision digital frequency demodulation with coarse-fine time-to-digital converter (TDC) and delay-locked loop (DLL). Furthermore, the front-end has a capability to apply pulse-controlled electrostatic(More)
