“…Furthermore, OOK allows for flexibility in the pulses shape, number of pulses per symbol and energy per pulse in order to choose the optimum solution for different conditions. A reconfigurable low power OOK transmitter has recently been proposed in [3]. Accordingly, this work presents a flexible OOK receiver that is meant for use with this transmitter.…”

This paper presents a 0.13 μm CMOS impulse radio ultra-wideband receiver which supports the on-off keying modulation scheme. The receiver includes a wideband low-noise amplifier, and allows for control of the integration window to accommodate different number of pulses per symbol at bandwidths of up to 10.6 GHz. A power cycling scheme is implemented to reduce the power consumption, and allows the system to operate within stringent power requirements. The receiver was simulated at data rates of 10 Mbps with a maximum simulated power usage of 4.5 mW. Power cycling reduces the power consumption by a factor of 3.3.

An on-off keying impulse radio ultra-wideband transmitter with frequency tuning ability based on a 0.13 µm CMOS process is presented. The output spectrum frequency and bandwidth can be adjusted using a digitally programmable oscillator in the 3.7 to 9 GHz range. This allows for the dynamic adjustment of the output spectrum to the surrounding environment. A fully integrated power cycling scheme is used to reduce significantly the power consumption. The transmitter achieves data rates of 10 Mbps with a simulated power consumption of 1.5 mW.I.
