|A voltage controlled di erential injection locked frequency divider (VCDILFD) with a large locking range is designed in a 0:24 m CMOS technology. A 29% locking range is achieved by an optimal inductor design and also by employing high Q accumulation mode MOS varactors to change the free{running oscillation frequency of the divider. The measurement results show frequency division at 5GHz with m...

In this paper a low-power current-mode RMS-to-DC converter is proposed. The proposed converter includes absolute value circuit, squarer/divider circuit, low-pass filter and square root circuit which employ CMOS transistors operating in weak inversion region. The RMS-to-DC converter has low power consumption (<1μW), low supply voltage (0.9V), wide input range (from 50 nA to 500 nA), low relative...

A CMOS current divider using a two-variable second-order Taylor series approximation is proposed. The approximation divider is realized with a compact circuit. The simulation results indicate that the approximation divider is feasible for the characteristics of sufficient accuracy, small distortion, and high bandwidth.

In this paper, we present a broadband out-of-phase power divider with high power-handling capability. The proposed device consists of several sections of double-sided parallel-strip lines (DSPSLs), a mid-inserted conductor plane, and two external isolation resistors, which are directly grounded for heat sinking. A through ground via (TGV), connecting the top and bottom sides of DSPSLs, is emplo...

In this paper analog advantages including low die area, high speed and simplicity are added to the digital advantages, such as programmability, robust against noise and distortions. a new programmable Fuzzifier circuit based on mixed-signal input, and min circuit for inference and Multiplier/D...

A generalized two-way coupled-line power divider with extended ports for dual band is proposed in this paper. The power divider is composed of two section coupled-lines, one conventional transmission line, and an isolation resistor, and employs extension of a transmission line or coupled-line at each port. The design equations are obtained based on evenand odd-mode analysis, and analytical idea...

This paper presents an approach to the design of a novel dual-band power divider with variable power dividing ratio. To achieve dual-band operation, a novel dual-band quarter-wave length transformer based on coupled-lines is proposed, which is used to replace the quarter-wave length transformer in Wilkinson power divider. The proposed dual-band power divider features a simple compact planar str...
