Single Acoustic Channel SAW Sensor With Ladder-type Transducers

This work presents the design, fabrication, and validation of a surface acoustic wave (SAW) sensor utilizing ladder-type interdigital transducers (LIDTs) and direct group delay measurements. By exploiting the LIDT multi-subchannel structure, sensing and reference channels are integrated into a single device, significan...

A New Binary Search Based ADC Architecture

This paper proposes and demonstrates a new ADC (Analog-to-Digital Converter) architecture based on a binary search strategy. The proposed topology uses a single voltage divider to generate the reference for comparison with the input sample. Depending on the comparator’s output, the maximum or minimum levels of the volt...
