Reliability Performance of a 70-GHz Mixer in 65-nm Technology

BPF-Based Thermal Sensor Circuit for On-Chip Testing of RF Circuits

“…More recently, temperature measurements are done in high frequency analog circuits to perform testing applications. The test of high frequency analog circuits is a challenging task, as the presence of a defect or the effects of process-voltage-temperature variations and device aging, does not usually produce a catastrophic circuit failure, but a degradation of circuit performance and specifications [ 21 , 22 , 23 , 24 , 25 ], which compromises yield. A strategy to compensate these performance degradations is to build in monitor circuits with the analog circuit (called hereafter the circuit under test (CUT)) to track variations in their performance [ 26 , 27 , 28 , 29 , 30 ] and, in the eventual case of detecting a circuit degradation, to activate a feedback in the CUT bias to compensate for them.…”

Investigation into the Relationship Between Conversion Gain, Local Oscillator Drive Level and DC Bias in a SiGe Transistor Transconductance Modulated Mixer at 24-28 GHz

“…Diode mixers are also popular [4] but usually require higher LO drive powers. Many integrated mixers use the well-known Gilbert Cell mixer strategy [5], [6], requiring several transistors. However, at mmWave frequencies, there is much attraction in simple circuit concepts that are reliable and power-efficient whilst using few active devices.…”

“…Besides, the mixer should provide some gain to suppress noise contributions from successive building blocks, such as basedband amplifiers and ADC. How to realize a high linearity, high gain and low noise mmW mixer has become a research hotspot [15,16,17,18,19,20,21,22,23,24,25].…”
