Abstract In this paper, a current-mode square/triangular wave is presented. Due to operation in current-mode, the proposed circuit provides a wide frequency response, a low supply voltage, low power consumption and electronic controllability. Thus, it is very suitable for use in portable and battery-powered equipments. The proposed square/triangular wave generator consists of merely current mod...

A compact and low-power design of a 12-bit binary-weighted current-steering DAC is presented. Instead of 4096 unit current cells, the proposed design uses 192 unit current sources with two reference currents. The silicon area of the generation circuit of two reference currents is very compact as well. The area of the total current source arrays is smaller than four times the area of 6-bit curre...

As large-scale wind power has been and will be integrated into power grid, traditional Active Power Dispatch and Control (APDC) system has encountered new challenges. In this paper, the active power dispatch mode of interconnected power grids which is suitable for the large-scale integration of wind power is analyzed firstly. Secondly, it is pointed out that traditional decentralized balance co...

At a highly automated facility in Oelde, Germany, high end appliance manufacturer, Miele produces around 300,000 electric ovens and cookers per year, all of which are comprehensively tested before delivery. To this end, the corresponding manufacturing cells are equipped with semiand fully-automatic testing stations. These stations benefit from integrated engineering and the close interaction of...

Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...

This paper describes the design of a high-efficiency energy harvesting circuit with an integrated antenna. The circuit is composed of series resonance and boost rectifier circuits for converting radio frequency power into boosted direct current (DC) voltage. The measured output DC voltage is 5.67 V for an input of 100 mV at 900 MHz. Antenna input impedance matching is optimized for greater effi...

Thermal effects are becoming increasingly important during integrated circuit design. Thermal characteristics influence reliability, power consumption, cooling costs, and performance. It is necessary to consider thermal effects during all levels of the design process, from the architectural level to the physical level. This is challenging because design-time temperature prediction requires acce...

This paper focuses on InP-based, HEMT Monolithic Millimeter-wave Integrated Circuit (MMIC) power amplifiers for applications to heterodyne receivers, transmitters, and communications circuits. Recently, we have developed several HEMT MMIC circuits using HRL Laboratories' 0.1 um InP HEMT technology with unprecedented high frequency performance and output power. Our results include an 80 GHz band...
