Capacity Building

Capacity Building Initiative

To evaluate and address the challenging areas in microelectronics field and creation of an enabling environment, DIT has a dedicated capacity building programme. Identifying Analog Mixed Signal domain as one of the very important area in the field of microelectronics, DIT had initiated projects in this crucial area at institutions of repute across country namely CEERI Pilani, IIT Madras and IISc Bangalore. The core areas of application covered include instrumentation applications, wireless communication systems, high speed signal processing as applied to data communication and data conversion. Other areas taken up for capacity building and expertise generation are VLSI design, MEMS and Human resource development in the area of VLSI Design.

Software package for 2-stage op-amp circuit

A software package OpAmp DESIGN for 2-stage op-amp circuit has been developed by IIT Kharagpur. OpAmpDESIGN is a computer aided design tool for different CMOS operational amplifier topologies such as miller-compensated two stage opamp. For a given specification, it finds "optimum" sizes of different MOS transistors and values of resistors and capacitors with which the circuit meets the specification requirement. Typically, the design time is within 100 seconds.

In this release the following two topologies have been incorporated:

(i) Miller-compensated Two-stage Opamp (input devices are NMOS)

(ii)Miller-compensated Two-stage Opamp (input devices are PMOS)

Low Temperature Co-fired Ceramic (LTCC) Facilities

A State-of-the-art facility for Advanced Processing Capabilities in LTCC is set up in the country jointly supported by NPMASS-DRDO and DeitY at C-MET Pune. Infrastructure has been created to handle the advanced applications in LTCC such as high density interconnects, microfluidics and micro-sensor packaging.
