This paper presents a novel readout circuit of uncooled, bolometer-based, focal plane arrays (FPAs). The offset and flicker noise are the design challenges of microbolometer readout circuits (ROCs). The ROC is not only required to apply careful noise cancellation techniques, but also to be insensitive to process and supply voltage variations. The proposed(More)
In this paper we present an offset cancellation technique for a comparator used in SAR (successive approximation register) analog to digital converter improving the signal to noise ratio of the whole system with minimum power consumption at the expense of complexity of the system. An 8-bit SAR ADC is presented with power consumption 22nW, ENOB = 7.051 and(More)
This paper investigates memristor based demodulators and proposes new circuit designs for Binary Frequency Shift Keying (BFSK) and circular 8-Quadrature Amplitude Modulation (QAM) demodulators using two memristors at most. The proposed designs consider utilizing the unique features of the memristor element, crucially, its variable average memristance with(More)
This paper presents an ultra-low-power boost converter for indoors photovoltaic energy harvesting applications. The boost converter, working in the discontinuous conduction mode (DCM), utilizes an active diode (AD) technique to avoid negative current flowing in the inductor and a control technique that allows supplying dual output voltage levels with(More)
