More on: TI’s on-chip bulk acoustic wave oscillator to replace external crystals

Texas Instruments has removed the need for external timing crystals by developing a technique for building high-grade thin film piezoelectric bulk acoustic wave (BAW) resonators within the metallisation of silicon chips, on a CMOS-compatible process that can be delivered in a standard, or even thin, QFN package. The crucial piezo film is sandwiched between two ...
