Analog Circuit Testing Using Built-In Direct-Digital Synthesis
نویسندگان
چکیده
Linearity is an important measure of an analog amplifier performance and normally measured by the 3rd order inter-modulation product (IP3) under a two-tone test. In this paper, we propose a test scheme that generates test tones using a built-in direct-digital synthesizer (DDS). Radio Frequency (RF) test tones are generated by converting the DDS output to RF using a built-in analog mixer that can be the building block of a RF transceiver.

Look up Table Based Low Power Analog Circuit Testing
In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...
متن کاملPhase Delay in MAC-based Analog Functional Testing in Mixed-Signal Systems
A Built-In Self-Test (BIST) approach has been proposed for functionality measurements of analog circuitry in mixed-signal systems. The BIST circuitry consists of a direct digital synthesizer (DDS) based test pattern generator (TPG) and multiplier/accumulator (MAC) based output response analyzer (ORA). In this paper we investigate and discuss the effects of phase delay on analog functionality me...

This thesis focuses on a digital Built-in Self-Test (BIST) approach to perform specification oriented testing of the analog portion of a mixed-signal system. The BIST utilizes a direct digital synthesizer (DDS) based test pattern generator (TPG) and a multiplieraccumulator (MAC) based output response analyzer (ORA) to stimulate and analyze the analog devices under test, respectively. This appro...
متن کاملA Tutorial Introduction to Research on Analog and Mixed-Signal Circuit Testing
Traditionally, work on analog testing has focused on diagnosing faults in board designs. Recently, with increasing levels of integration, not just diagnosing faults, but distinguishing between faulty and good circuits has become a problem. Analog blocks embedded in digital systems may not easily be separately testable. Consequently, many papers have been recently written proposing techniques to...
