High-resolution data converter IP (ADC/DAC)

Roughly ten nations hold the capability to design high-resolution analog-to-digital and digital-to-analog converter IP. India is not among them. As of 2024, effectively all of India's high-resolution converter IP is sourced externally.

An ADC translates the continuous voltages of the physical world — a radar echo, a heartbeat, a radio signal — into the discrete numbers a processor can act on; a DAC runs the process in reverse. They are the interface between the analog world and every digital system that reads or drives it. That places them inside defence electronics, space systems, 5G and 6G telecom, autonomous vehicles and medical devices.

The difficulty is that these are among the hardest analog circuits to build well. Resolution and speed depend on precision voltage and current references, low-noise comparators, switched-capacitor networks and mixed-signal process technology, all held to tolerances where a few millivolts of drift degrades the whole part. Silicon then has to be validated for noise, linearity and spurious-free dynamic range before it can be trusted. The global high-speed data converter market was worth USD 3.7 billion in 2024, and its design capability sits almost entirely in North America, Europe and East Asia. Analog Devices, Texas Instruments and Microchip Technology lead it. North America alone accounts for 87.7 per cent of the market.

India's position is early. The Semiconductor Laboratory (SCL) at Chandigarh, under ISRO, lists data converters, amplifiers and drivers within its 180-nanometre CMOS portfolio, but there is no public evidence of high-resolution ADC/DAC IP reaching working prototypes, tapeouts or commercial licensing; its output is oriented toward niche space and defence components. The wider design ecosystem is growing — as of January 2026 the Design Linked Incentive scheme had approved 23 chip design projects and supported over 70 firms with EDA tools and foundry access — but none is documented as explicitly targeting converter IP.

The gap persists because the foundations sit at uneven heights. Analog circuit design, precision references and high-speed comparators are demonstrated in India. The layers above them — sub-180nm mixed-signal process technology, switched-capacitor design, and high-resolution testing and characterisation — remain emerging. A converter is only as good as its weakest supporting capability, and precisely those are the least mature.

Closing it would mean lifting those emerging dependencies to production maturity, then pairing them with the industrial EDA tools already available in-country to carry a design through validated silicon. The building blocks exist; the integrated, characterised, high-resolution part does not yet.
