IN BRIEF:

As one of the key departments of silicon IC design in IMECAS,   ASIC & System Dept. was established in 1986. Many national key projects had been completed in the 7th,   8th,   9th and 10th Five-Year periods,   and a lot of high level talents in IC design had been fostered.

The aim of this dept. is to pursue the cutting edge trend of IC design,   to meet the requirements of national and international IC development,   to be a leader in IC application,   and to cultivate high-level experts of IC design.

This dept. now has 21 technicists,   including 6 senior staffs,   and focus on high speed digital signal processing,   low power design,   high performance analog and RF IC design.

In 2004,   an ultra high speed DSP chip whose maximum speed can be 25.6 billion times of MAC per second was successfully developed,   reaching internationally advanced level. 78 technique papers and 26 patents have been published in the latest 5 years. Meanwhile,   recently this lab presented 4 invited reports at international conferences and was invited to be the co-chairman of RF/mixed-signal UWB Transmitter subcommittee of the ICSICT-2006. Till now 18 students have gotten their Master or PhD degrees and began to play important roles in their research work.

This dept. consists of three labs: Real-time Signal Processing,   Mixed-Signal and CMOS RF & Analog Lab.
RESEARCH FOCUS:

1. High Performance Real-time Signal Processing Lab

This team’s research field consists of massive-data high-performance specific digital signal processor,   reconstructive processor architecture,   million-gate-level deep submicron VLSI design,   software and hardware co-verification of high-performance real-time signal processing SoC systems,   high-performance reconstructive real-time signal processing hardware platform based on FPGA & co-processors,   and so on. We have already developed a sound design flow which includes the definition of design rules,   arithmetic simulation of system,   the design and implementation of hardware system. We have also developed ultra high speed reconstructive digital signal processor which can complete tens of billions of float-point operation per second,   achieving world-leading level,   and built the whole platform of high-performance real-time signal processing hardware system based on FPGA & co-processors.

Research projects: the architecture of high-performance reconstructive digital signal processor,   deep sub-micron integrated circuits and SoC design,   high-performance reconstructive digital signal processing platform.

Application Areas: wide-band communication and software wireless radio,   portable TV system,   radar technology,   sonar technology,   real-time image processing,   biological and medical electronics,   etc.

2. Mixed-Signal ICs Design Lab

The members in this lab mainly focus on the theory and cutting edge technology of mixed-signal IC,   including low power circuit design,   deep submicron physical implementation and design for reliability. The projects we are working on now include passive RFID,   high speed/high resolution ADC,   high speed IO,   energy recovery circuit and ESD protection circuit and CMOS circuit design reinforce technology. We study from circuit design level to physical implementation and from aspect of reliability to reach high performance and high stability. We also supply the same qualified & standard design solution and service as a company does. Our team owns many patents and has many articles published on top international magazines and conferences. Every member of this team has rich experiences in mixed-signal IC design and physical implementation.

In the field of physical implementation,   we successfully designed and taped out many digital ICs,   such as an ASIC with 5 million gates,   and in the packing stage,   we helped manufacture solve the problem of too many IO pins.

3. CMOS RF & Analog ICs Design Lab

This lab engages in analyzing and research of physical characteristic of RF and analog signals in CMOS ICs (Integrated Circuits) process,   design of CMOS integrated RF transceivers for special applications. Research fields in this lab include LNA,   high-frequency CMOS mixer,   high-gain high-tunable-range and high-linearity VGA,   high-frequency PLL,   all kinds of Analog-to-Digital Converters and high-frequency CMOS RF circuits. At present,   it is emphasized on R&D of CMOS full integrated satellite receivers for 4GHz frequency band application.

The application fields include wireless communication system modules,   such as GPS (Global Position System),   WLAN (Wireless Local Area Network) and Bluetooth.
