In this paper, a new design for a low power CMOS flash Analog-to-Digital Converter (ADC) is proposed. A 6-bit flash ADC, with a maximum acquisition speed of 1GHz, is implemented in a 1.2 V analog supply voltage. HSpice simulation results for the proposed flash ADC verifying the analytical results are also given. It shows that the proposed 6-bit flash ADC consumes less power i n a commercial 90n...

Active triangulation is a well-established technique for collecting range data. Use of low-power systems in environments with high ambient light is motivated by considerations of price, portability and eye safety. However, when environment light is high, detection of laser return can be challenging. A method combining filtering of specialized low-level features with dynamic programming is propo...

Recently, low-power wireless networking standards like 802.15.1 (Bluetooth) have driven consumer interest in personal area networks (PANs). These networks are designed for inexpensively connecting low-power devices located within 1 m to 100 m of each other. In this paper, we discuss recent evolutions to the Bluetooth standard, as well as two emerging PAN standards: 802.15.4/ZigBee, and Ultra-Wi...

Subject matter of this paper deals with issues of the environmental impact of infrasound noise associated with operation of low-power wind turbines. It is now the current and relevant problem for both the cognitive and utilitarian standpoint. There is now a considerable growth in the number of such installations in Poland, Europe and in the world, due to the possibility of locating them on exis...

In this letter a useful CMOS fully-differential buffer topology is presented. The proposed solution, performing the common mode feedback (CMFB) operation, shows a rail-to-rail characteristic, so it is particularly suitable for low-voltage (± 0.75V) low-power (<400 μW) applications. The simulated results have shown excellent general performance, evaluated in terms of suitable figures of merit (F...

Since stream ciphers have the reputation to be inefficient in software applications the new stream cipher Hermes8 has been developed. It is based on a 8-bit-architecture and an algorithm with low complexity. The two versions presented here are Hermes8-80 with 23 byte state and 10 byte key and furthermore Hermes8-128 with 37 byte state and 16 byte key. Both are suited to run efficiently on 8-bit...

In this paper, a low-power adaptive low noise amplifier (LNA) is presented. The LNA is based on a bipolar cascode topology, uses inductive source degeneration and emitter area scaling to achieve noise and input-impedance matching simultaneously. The input impedance and the noise factor were simulated as function of the bias collector current and the results show that both are approximately cons...
