—This paper proposes a novel phase-locked loop (PLL) frequency synthesizer using single-electron devices (SEDs) and metal-oxide-semiconductor (MOS) field-effect transistors. The PLL frequency synthesizer mainly consists of a single-electron transistor (SET)/MOS hybrid voltage-controlled oscillator circuit, a single-electron (SE) turnstile/MOS hybrid(More)
—This paper proposes a novel programmable vision chip based on multiple levels of parallel processors. The chip integrates CMOS image sensor, multiple-levels of SIMD parallel processors and an embedded microprocessor unit (MPU). The multiple-levels of SIMD parallel processors consist of an array processor of SIMD processing elements (PEs) and a column of(More)
A programmable vision chip with variable resolution and row-pixel-mixed parallel image processors is presented. The chip consists of a CMOS sensor array, with row-parallel 6-bit Algorithmic ADCs, row-parallel gray-scale image processors, pixel-parallel SIMD Processing Element (PE) array, and instruction controller.

This paper proposes an ultra-low power CMOS random number generator (RNG), which is based on an oscillator-sampling architecture. The noisy oscillator consists of a dual-drain MOS transistor, a noise generator and a voltage control oscillator. The dual-drain MOS transistor can bring extra-noise to the drain current or the output voltage so that the jitter(More)
SUMMARY A single-electron turnstile and electrometer circuit was fabricated on a silicon-on-insulator substrate. The turnstile, which is operated by opening and closing two metal-oxide-semiconductor field-effect transistors (MOSFETs) alternately, allows current quantization at 20 K due to single-electron transfer. Another MOSFET is placed at the drain side(More)
In this paper, we present an improved charge pump circuit for the non-volatile memories in RFID tags. The circuit consists of a single pumping branch without auxiliary capacitors and operates with a simple two-phase clock. The internal high voltages are used to control the gate and bulk terminals of the charge transfer switch. As a result, the threshold(More)
