This paper proposes a new arbitrary nonlinear transfer function generator circuit based on pulse-phase modulation. The circuit can generate an arbitrary non-monotone function with an identical circuit con guration. Chaotic signal generators using this function generator are also proposed. Circuit simulation results demonstrate that the new approach achieves high precision transformation. These ...

this paper proposes a buffer circuit for footed domino logic circuit. It minimizes redundant switching at the output node. This circuit prevents propagation of precharge pulse to the output node during precharge phase which saves power consumption. We have calculated the power consumption, delay and power delay product of proposed circuits and compared the results with existing domino circuit f...

This paper presents the development of delay pulse circuit with 1ns resolution for both driving ultrasonic array transducers and digital receive beamforming for ultrasonic phased array system. The circuit which can supply pulses with a 1ns time resolution employs the phase shifting with phase locked loop (PLL). In this way, 6 phase clocks with 1ns phase difference are generated, which are used ...

For the past several years, much progress has been made in Low power VLSI Design .In This paper ,a novel low-power pulse Triggered flipflop design is presented. First, the pulse generation control logic an AND function, is removed from critical path to facilitate a faster discharge operation. A simple two-transistor AND gate design is used to reduce the circuit complexity. Second, a conditional...

A robust cellular counter could enable synthetic biologists to design complex circuits with diverse behaviors. The existing synthetic-biological counters, responsive to the beginning of the pulse, are sensitive to the pulse duration. Here we present a pulse detecting circuit that responds only at the falling edge of a pulse-analogous to negative edge triggered electric circuits. As biological e...

One of the important challenges in the emerging field of synthetic biology is designing artificial networks that achieve coordinated behavior in cell communities. Here we present a synthetic multicellular bacterial system where receiver cells exhibit transient gene expression in response to a long-lasting signal from neighboring sender cells. The engineered sender cells synthesize an inducer, a...

In modern world of communication system, a coded M-ary pulse position modulation (PPM) scheme for transmitted reference ultra-wideband (TR-UWB) systems is proposed. The modulation level M in conventional M-ary PPM TR-UWB scheme, is defined only with a number of possible pulse positions Z. So, Z radio frequency (RF) wideband delay lines are required in order to map data bits into the proper puls...

This paper sets forth the reliability analysis of conventional isolated pulse width modulation DC-DC (IDC-DC) converters. The IDC-DC converters are categorized into single-switch (ISSDC-DC) or multiple-switch (IMSDC-DC) proposed framework encompasses analyzing impacts duty cycle, input voltage, output power, transformer turns ratio, components characteristics and time duration on overall perfor...
