Abstract :
This paper presents a Ka band prescaler in a general-purpose 90nm SOI CMOS process (CMOS090_SOI). Hereby, a D-latch concept is introduced. A stack inductor enhances its high frequency performance and reduces the sensitivity with process variations and temperature. The prescaler version with stack inductor has the minimum sensitivity at 31 GHz with an operation range of 13 to 34GHz. The prescaler without inductors has an operation range of 9 to 27GHz with minimum sensitivity at 23GHz. At 1MHz offset from the carrier, the phase noise of the divider amounts -127dBc/Hz. For on-wafer testing, the two versions of the prescaler were implemented in a 90nm SOI CMOS process (CMOS090_SOI) with six metal layers and one thick top metal layer. The divider consumes 60mW from a 1V supply voltage and the active area is 350 × 400μm2.
