“…The second order characteristic equation of the oscillator is given by: with the transconductance ratio k=g m6 /g m7 . Equations (18), (19) and (21) show the different expressions for frequency ω o , quality factor Q and oscillator parameter b. Ideally we can tune the oscillator frequency via g m2 and g m4 and adjust quality factor via g m3 for KHN bandpass filter without affecting the amplitude of the oscillation of the converted oscillator.…”

“…To increase the fault coverage of OBT, [8,[16][17][18] combined measurement of both the oscillator's frequency and amplitude which means more test costs. For the ladder filters that can not be partitioned, alternative way to applicate OBT have been addressed in [19][20][21]. [22] presented a new performance characterization of OBT by using parametric fault models and evaluated the ability of the addressed test strategy for testing two fifth order low pass filters.…”

This paper describes a design for testability technique for second-order bandpass operational transconductance amplifier and capacitor filters using an oscillation-based test topology. The oscillation-based test structure is a vectorless output test strategy easily extendable to built-in self-test. The proposed methodology converts filter under test into a quadrature oscillator using very simple techniques and measures the output frequency. Using feedback loops with nonlinear block, the filter-to-oscillator conversion techniques easily convert the bandpass OTA-C filter into an oscillator. With a minimum number of extra components, the proposed scheme requires a negligible area overhead. The validity of the proposed method has been verified using comparison between faulty and faultfree simulation results of Tow-Thomas and KHN OTA-C filters. Simulation results in 0.25μm CMOS technology show that the proposed oscillation-based test strategy for OTA-C filters is suitable for catastrophic and parametric faults testing and also effective in detecting single and multiple faults with high fault coverage.

“…This new testing method has found use in many types of analog blocks: AD converters [1]- [3], filters [4]- [7], operational amplifiers [8] [9]. The main disadvantage of this method is that it is strongly dependent on the type and complexity of the circuit that is designed for test.…”
