Silicon bulk micromachined FBAR filter and Duplexer for advanced handset applications
This article presents a new circuit to generate a higher-order derivative Gaussian pulse for the impulse radio ultra-wideband(IR-UWB) communication systems. This IR-UWB pulse generator is de-signed and measured with the TSMC 0.18-m CMOS process. The cir-cuit is able to generate a symmetrical and low-ringing pulse in a fre-quency band from 3.1 to 10.6 GHz. Our work shows that the pulsegenerator’s output pulse width is 500 ps with an amplitude of 40 mV(peak to peak). The measurement results validate our design and thecircuit functionality.
