A digital-assist technique is experimentally demonstrated that tightens the conversion-gain (CG) flatness of a CMOS mixer from a baseline level of ±1.5 dB over a 1–12 GHz span to ±1.0 dB over a 1–15 GHz span. The method uses a microcontroller to find the optimal bias point of the mixer that produces the desired CG flatness.
The ability to accurately determine the breakdown voltage of microwave transistors is critical to the design of high power microwave amplifiers. The optimal bias point and output impedance should be selected to ensure that the load line of the device during peak output power does not intersect the portion of the IV curve where the device breaks down. This paper presents a technique to determine a...
This paper deals with the effects of direct current bias voltage to X-cut y conduction Mach-Zehnder intensity modulator's export optical power, and achieves a cosine function equation of direct current bias voltage versus export optical power of modulator. The modulator works on an approximate linear region nearby the optimal bias point Vpi/2(plusmn 10 mV). Considering the approximate linear region's...
