Low Power CMOS Re-programmable Pulse Generator for UWB Systems
In this paper we discuss the design of a CMOS based pulse generator for impulse-based UWB systems. The basic structure of our design involves a power amplifier with four control taps, which essentially decides the shape of the generated pulse. The design is versatile and may be used in a variety of UWB modulation schemes and systems. In addition, this design can also be incorporated into a mult...
متن کاملPulse Generator Monocycle Gaussian for UWB Applications
This paper focuses on the study and design of a simple MOS generator circuit which provides the first derivative of the Gaussian pulse from input rectangular signal. To generate wavelets required in an ultrawideband (UWB) impulse radio, the first derivative of the Gaussian function is approximated by combining four hyperbolic tangent functions (tanh). Afterwards, four differential pairs are use...
متن کاملAn N-Bit Digitally Variable Ultra Wideband Pulse Generator for GPR and UWB Applications
This paper presents a low-cost Ultra Wideband (UWB) pulse generator that can vary the pulse duration digitally by using a Step Recovery Diode (SRD), microstrip transmission lines and PIN diodes. First, a sharp edge is generated by using a SRD circuitry. Then a pulse is formed from the sharp edge through the use of transmission lines and the PIN diodes. Based on the number of transmission lines ...
متن کاملA low power 3.1-7.5 GHz tunable pulse generator for impulse radio UWB
A novel energy-efficient tunable impulse radio ultra wide band (IR-UWB) pulse generator (PG) for the high data rate 3.1 − 7.5 GHz band applications is proposed. Glitch generator, switched ring oscillator, buffer and pulse shaping filter are the key components. The circuit is scalable both in bandwidth and center frequency. The glitch generator combines falling edge of the input signal and its d...
متن کاملUltra Low Power Symmetric Pass Gate Adiabatic Logic with CNTFET for Secure IoT Applications
With the advent and development of the Internet of Things, new needs arose and more attention was paid to these needs. These needs include: low power consumption, low area consumption, low supply voltage, higher security and so on. Many solutions have been proposed to improve each one of these needs. In this paper, we try to reduce the power consumption and enhance the security by using SPGAL, ...
