This work presents a compact ADC architecture capable of digitizing the signals received by every individual element of a 2D ultrasound transducer array. An element-matched layout of 150 μm × 150 μm is realized by exploiting each piezo-electric transducer element not only as the signal source, but also as the electro-mechanical loop-filter of a continuoustime band-pass ΔΣ ADC, thus minimizing the...
A compact dual-band monopole antenna for WLAN applications is proposed and investigated. The proposed antenna is basically composed of two strips and an asymmetric microstrip-fed line. The measured results show the proposed antenna can provide two separate impedance bandwidths of 150 MHz (about 6.1% centered at 2.45 GHz) and 1124 MHz (about 18.2% centered at 5.5 GHz), making it easy to cover the specifications...
