Abstract :
A “GaAs on Si” PLL frequency synthesizer IC has been developed using chip on chip technology. Chip on chip technology offers refined devices to integrate more than two chips into a single IC package. It is suitable for applications like pagers where small size is the most important factor. The device incorporates a GaAs prescaler as a daughter chip and a CMOS PLL as a mother chip. The power consumption is 6 mW at VDD=1 V, the operating frequency is 800 MHz
