A complementary LC-tank based IR-UWB pulse generator for BPSK modulation

Abstract

This paper presents a low-power binary phase shift keying (BPSK) pulse generator for ultra-wide-band transmitters. The circuit has been designed based on LC-tank resonators using 0.13 um CMOS technology. Simulation shows-10dB bandwidth of around 3 GHz and power consumption of 2 mW at 100 MHz PRF. Peak-peak amplitude voltage for both symbols '1' and '0' are approximately as large as 1.2V supply voltage and can radiate enough energy to satisfy the FCC mask only by one pulse. Thus, the energy consumption is 20 pJ/pulse/bit. Pulse duration is 1.5 ns and the transmitter can reach data rates of 660 Mbps

Analysis of Consumer Behavior in Reverse Logistic Polyethylene Terephthalate in Indonesia Towards a Circular Economy

“…Previous research on consumer behavior after plastic consumption and recycling, including Kianpour et al [11], identifies potential factors to reduce consumer behavior in plastic consumption. Khan et al [4] identify factors influencing consumer intent on the return/recycling of plastic waste.…”

“…Its success is primarily determined by Reverse Logistics, as the flow of products from consumers to producers in distribution channels. Reverse logistics involves collecting used products from end users/consumers, sorting products for return and processing at recycling plants, and redistributing those products to manufacturers [10], [11]. It is the consumer who acts as a supplier in reverse logistics.…”
