Abstract
Traditionally, radio frequency (RF) paths are bypassed during wafer sort due to the high cost of RF testing. Increasing packaging costs, however, result in a need for a more thorough wafer-level testing including the RF path. In this paper, we propose a loop-back architecture, along with a novel, all-digital design-for-testability (DfT) modification that enables cost efficient testing of various defects at the wafer level. These methods are applicable to a wide range of cost-sensitive applications that use the modulation of the voltage-controlled-oscillator(VCO). Experimental results using a Bluetooth platform and considering a variety of defects confirm the viability of the approach.
