This brief presents an all-digital PLL (AD-PLL) for a DDR5 registering clock driver (RCD)
with a self-biased supply-noise-compensation (SNC) technique. By combining two Nagata …

This paper describes CMOS peaking current sources (Nagata current sources) with self-bias
configuration; they are insensitive to temperature as well as supply voltage. First the cross …

This paper describes silicon verification of our improved peaking current mirror, originally
invented by Nagata Minoru in 1966. Our improved MOS current mirror circuits are insensitive …

This paper investigates a feasibility of an IGBT driver with current sources to obtain good
trade-off between the switching loss and the output voltage overshoot. We consider here an …

This article reviews the author's group research achievements in analog/mixed-signal circuit
and system area with introduction of how they came up with the ideas. Analog/mixed-signal …

This paper describes an improved Nagata current source insensitive to temperature utilizing
MOSFET drain current temperature characteristics, as well as supply voltage variation. The …

This paper proposes two simple MOS reference current sources that are insensitive to
temperature variation, utilizing the temperature invariant bias point of the MOSFET IV …

In response to the urgent need for domestic nuclear reactor instrumentation and control
(I&C) systems, this study employs the NSA2860 chip, NSi8141 digital isolator, and …

As demands for wide-band operations increase and sub-rate architectures for reducing
power consumption in wireline communications become promising, a ring oscillator (RO) …

In this thesis, major concerns in the architecture of internal display interface are explained.
Considering the limited battery capacity of mobile phones and the increasing amount of …
