TxACE Sign

The centralized group of laboratories of the Texas Analog Center of Excellence dedicated to analog engineering research and training occupies a ~8000 ft2 area on the 3rd floor of the Engineering and Computer Science North building. The facility includes RF and THz, Integrated System Design, Embedded Signal Processing, and Analog & Mixed Signal laboratories as well as CAD/Design laboratory structured to promote collaborative research. The unique instrumentation capability includes network analyses and linearity measurements up to 325 GHz,spectrum analysis up to 120 THz, and cryo-measurements down to 2°K.


Lab equipment in designated facility


Last year, the researchers of TxACE have received approximately $1 million dollars through the Defense University Research Instrumentation Program to establish a dedicated multiple harmonic load and source pull measurement set up including pulsed measurement capabilities (up to 67 GHz for the third harmonic) and an antenna measurement set up that will allow measurements up to 325 GHz. The close proximity of researchers in an open layout enables natural interaction and compels sharing of knowledge and instrumentation among the students and faculty. The TxACE analog research facility is one of the best equipped electronics laboratories. The laboratory is available for use by TxACE researchers all over the world.
