Abstract

In this paper, a new Design for Testability (DFT) scheme is proposed, for the testing of LC-tank CMOS Voltage Controlled Oscillators (VCOs). The proposed test-circuit is capable of detecting hard (catastrophic) and soft (parametric) faults, injected in the VCO. The test result is provided by a digital Fail/Pass signal. Simulation results reveal the effectiveness of the proposed circuit. The overall silicon area requirement of the proposed DFT scheme is negligible.
