An 8 bit, 200 MHz BiCMOS comparator
- 1989
A BiCMOS comparator intended for use in low-power, high-speed analog-t-digital conversion systems operating at video frequencies and above is described. An experimental version of the comparator integrated in a 1μm BiCMOS technology performs comparisons at mtes up to 200 MHE.

A data flow image compression processor
- Trang 119-120 - 1989
This paper presents a binary image data compression and expansion processor that can compress 500 kbytes of image data into 35 kbyles of code data in 0.41 seconds. The processor equips with data flow hardware and CPU on the one chip. Topics described include the algorithms, architecture, and performance.

Soft-error characteristics in bipolar memory cells with small critical charge
- 1989
In this paper, first, the contribution of charge collected at the base and the collector to soft-error is investigated using computer simulation. Next, an effective charge model incorporating weight coefficients is proposed.

Automatic gain control (AGC) circuit for high density BiCMOS SRAM
- 1989
In this paper an Automatic Gain Control (AGC) circuit is discussed. This AGC circuit is applied to a high speed BiCMOS SRAM bitline scheme to control the bitline voltage swings so that they are independent of temperature, operation and process variations.

A review of superconducting three-terminal devices
- 1989
Superconducting three-terminal devices have been extensively given attention as one of future digital devices since Bcdnorz and Mueller discovered high-critical-temperature superconductivity in the La-Ba-Cu-0 system. The use of zero-resistance superconductivity and low noise cryogenics is expectcd for a limiting field of silicone semiconductor devices. In this paper, it is worthwhile to review som......

A latch-up like new failure mechanism for high density cmos dynamic RAM's - hysteresis in operating Vcc range
- 1989
AS the RAM has reached higher Integration, transistors have been miniaturized as well as the number of transistors on a chip has increased. Therefore, the substrate current generated by the RAM circuit due to impact ionization has increased drastically. In addition, since substrate impurity concentration has increased with the device scaling, the back-gate bias effect of a transistor has become st......

A 2 GHz clock direct frequency synthesiser
- 1989
First results are now available on a U.H.F. capable Direct Frequency Synthesiser, (DFS) which is primarily intended for radar and E.W. applications. The device generates square, mangle and sine wave outputs, me and complement, phase and quadrature, over the range 1Hz to 500MHz.

An 8-bit 20 MS/s CMOS A/D converter with 59 mW power consumption
- 1989
Digital signal processing has been widely introduced in video systems. In these systems, CMOS A/D converters (ADCs) with low power consumption and small chip area are especially desirable as on-chip area are especially desirable as on-chip area are especially desirable as on-chip devices.

Design of a CMOS token ring LAN controller, TRC, compatible with IEEE802.5 MAC protocol
- 1989
Token ring has been increasing its importance among LAN (local area network) protocol as the need for deterministic response and low cost wirings continues to grow[1][2][3]. However, its complexity has caused multiple chip solutions for controllers, which are power and space consuming. Taking advantage of advanced CMOS circuits, we have newly developed a single chip high performance token ring con......
