Adaptive cancellations of systematic disturbances in a synchronous amplitude demodulator for sensors and instrumentation applications

“…Such an example is the processing of the resolver amplitude modulated signals in resolver-to-digital (R/D) converter [8,9]. In nonideal resolver due to the harmonic distortion, an additive DC bias and harmonics contents is present in the output, which degrades the performance of many R/D converters.…”

“…The filter method [1] is commonly used when the delay introduced by the filtering is tolerable. On the contrary, when such delay becomes detrimental, synchronous techniques are employed [2,3,8,9]. The technique in [2] is faster in settling time when compared to the filter method, which, however, is at the cost of precise clock timing relations.…”

Software Resolver-to-Digital Converter for Compensation of Amplitude Imbalances using D-Q Transformation

“…This is also calculated by Eqs. (13) and (14) and Dr value becomes maximum value A and Qr becomes zero. The conventional ATO uses Eq.…”

OTA-Based Sine-to-Triangular Wave Converter

“…From equation (1), an input signal voltage v A ≥ 3V T will cause the output current i 1 to closely rise to the bias current I B2 . Thus, the scaling factor m can be obtained by linear approximation of the large signal transfer characteristic of OTA 2 at a signal voltage v A = nV T for n ≥ 3, that is,…”

“…Many further references to its application can be found in the literature [1], [2], [4], [6]. The synthesis of an inverse sine function can be realized in the form of an analog circuit technique and a digital computation technique.…”
