Latest Patents
One of his latest patents is a high output power digital-to-analog converter system. This design is tailored for high-speed applications, particularly in radio frequency contexts. The digital-to-analog converter (DAC) utilizes a parallel DAC structure, featuring eight parallel DACs that provide an aggregate current output. This design allows for a high and programmable current output, reaching up to 512 mA or more in some implementations. The parallel structure effectively addresses the challenges associated with outputting high current levels using a single DAC. Furthermore, the DAC design incorporates a hybrid structure that integrates the signal chain, enhancing system reliability. In certain embodiments, this hybrid structure employs a CMOS process for current sources and switches, along with a GaAs cascode stage for output combination. This combination optimally leverages the strengths of both technologies, resulting in a highly efficient DAC with peak output power programmable up to 29 dBm or more.
