A 10Ms/s 11-b algorithmic ADC with an active area of 0.19mm is presented. Using an improved clocking scheme, this design overcomes the speed limit of algorithmic ADCs. The proposed ADC employs amplifier sharing, DC offset cancellation, and input memory effect suppression to reduce area and power, and achieve high linearity. The ADC implemented in a 0.13μm thick gate-oxide CMOS process achieves ...
Owing to low voltage stresses, wide range of input and the same polarity output voltage, double-switch buck-boost converter (DSBBC) is a popular choice achieve dc/dc conversion in photovoltaic generations (PV), power factor correction (PFC), portable devices so on. Combined control (CC) makes DSBBC operate efficiently, but large ripples are unavoidable during mode transition. With two equal dut...
The thermoelectric transfer difference of Thermal Converters (TCs) can be evaluated in both current mode and voltage mode, using a fast-reversed dc (FRDC) source. Some types of TCs show differences in the thermoelectric transfer difference between voltage and current mode as large as some parts in 10. In order to investigate the origin of the discrepancy, the change of the thermoelectric transf...
Abstract Two different DC offset compensators for sensorless PMSM, motor drives with wide speed range flux linkage observers, are introduced and compared. The first one is an improved observer PI correction no need mover phase adaptation. second a novel active disturbance rejection controller (ADRC) compensator without ESO built into ADRC able to detect compensate both internal model external l...
