The Problem

Analog design is hard.
Vanishingly few people can do it.

Unlike digital, which has been largely automated for decades, analog IC design remains a manual craft — demanding years of specialist intuition. The world is running out of analog designers just as demand accelerates.

Continuous · Infinite resolution
Analog Signal

Voltage varies continuously. Every point on the scale is a valid, distinct value — infinite resolution, but hard to design.

Digital Signal

Only discrete states exist. 3 bits encode 5 fixed levels — simple to automate, but resolution is bounded by bit-depth.

Why Analog

Where analog has
no substitute.

The physical world is analog. Wherever circuits must interface with reality — signals, power, sensors, RF — analog wins on efficiency and fidelity by fundamental physics.

RF & Wireless

Every 5G basestation and Wi-Fi chip relies on analog LNAs, mixers, and VCOs to process GHz-range signals at sub-milliwatt power. No digital equivalent exists.

Power Management

LDO regulators and DC-DC converters keep digital logic alive at efficiencies above 95%. Their analog feedback loops respond in nanoseconds.

Sensing & ADCs

Biosensors, MEMS microphones, and precision amplifiers extract microvolt signals from the environment — dynamic range no digital chain can match.

High-Speed I/O

At 112 Gbps and beyond, signal integrity is a physical, analog problem. CTLE and DFE equalisers are analog circuits inside every data-centre interconnect.

The Design Gap

Digital design was transformed by synthesis and place-and-route in the 1980s. Analog never got that revolution — designers still size transistors by hand, navigating noise, matching, and layout parasitics invisible to digital abstraction.

The Unprecedented Opportunity Now

From prompt to
tapeout-ready file.

The automation of analog chip design has gone from impossible to inevitable. AI can now learn human design intuition, dramatically increase throughput, and dismantle one of hardware's most stubborn bottlenecks. Samurai is leading that revolution — starting with schematics.

Samurai is the Cursor moment for analog — bringing the same automation leap to software engineering, fuelled by AI, to analog chip design.
01

Describe your spec

Input target parameters — gain, bandwidth, supply voltage, topology — in plain English.
02

LLM synthesizes the schematic

Our model generates a hierarchical netlist complete with component sizing, bias networks, and feedback paths — encoding the design intuition of expert analog engineers.
03

Automated simulation

Cloud SPICE runs AC, DC, and transient sweeps. The model iterates until specs converge across process corners and Monte Carlo.
04

GDSII export

Layout is placed and routed with DRC/LVS clean guarantee. Export directly to your fab's PDK portal, ready for tapeout.

The Team

World-class training meets years of domain expertise.

British engineering has shaped the foundations of modern electronics — from radar to the BBC Micro to ARM. We're proud to be building its future here too. The founding team sets off with Oxford and Cambridge foundations, forty years of hands-on expertise, and a vision to unlock what analog design has never before been able to achieve.
