Conventional A/D conversion is performed by comparing the input signal voltage with the reference voltage. On the other hand, by dividing and comparing the output voltages of two amplifiers with different reference voltages with the same input signal voltage, it was found that A/D conversion can be performed. This A/D conversion method is called interpolated A/D conversion.

This conversion method enables smooth A/D conversion with a small DNL without adjusting the gain of the amplifier or the reference voltage, and also enables low power consumption by reducing the number of amplifiers.

In this talk, we will introduce not only the principles and effects of interpolated A/D conversion, but also conceptual methods in circuit development, such as generalization by intuition and formulation that gave rise to unique A/D conversion methods.

A resistive-interpolated Bi-CMOS ADC was developed for home HDTV receivers. A capacitive-interpolated CMOS ADC reduced the power consumption to 1/8 of other ADCs was developed for the portable digital video equipment such as a handy camcorder. A gate-width interpolation CMOS ADC achieved ultra-high-speed operation of 400 MS/s and 1/10 the power consumption of the other ADCs. It is embedded on the world’s first one-chip Mixed Signal SoC for DVD and contributed higher performance and lower cost of DVD recorders.

In this talk, we would like you to understand that the interpolated A/D conversion method is not just an idea but was created for the development of A/D converters with high performance and low power in order to realize the new electronic devices.

Advanced electronic/optoelectronic technologies designed to allow stable, intimate integration with living organisms will accelerate progress in biomedical research; they will also serve as the foundations for new approaches in monitoring and treating diseases. Specifically, capabilities for injecting miniaturized electronic systems and other components into soft tissues or for softly laminating them onto the surfaces of vital organs will open up unique and important opportunities in tracking and manipulating biological processes. This presentation describes the core concepts in materials science, circuit design and manufacturing that underpin these types of technologies, including bioresorbable, or ‘transient’, devices designed to disappear into the body on timescales matched to natural processes. Examples include skin-like devices for health monitoring and bioelectronic ‘medicines’ for neuroregeneration and temporary cardiac pacing.
