A temperature sensor used to compensate the crystal oscillator frequency instability of a real time clock (RTC) is proposed in this paper. The sensor utilizes the difference of a current proportional to the absolute temperature (PTAT) and another complementary to the absolute temperature (CTAT), generating a high-slope PTAT voltage with minimum value close to zero. The introduced approach provides...
This paper presents the accurate synthesis of a narrow-band CMOS Low Noise Amplifier (LNA) using an optimization-based approach. Multi-objective information and the corners of the fabrication process are used in the synthesizer to simultaneously optimize impedance matching, performance parameters and circuit robustness. The synthesis approach combines the Simulated Annealing algorithm with the crossover...
