Custom ASICs are often deployed in sensor read-out electronics. These read-out systems tend to be unique and require the custom ASIC to

• realize the unique functions at the power dissipation suitable for the system,
• reduce cost and
• protect intellectual property.

This article walks through the key elements of a custom solution for a Sensor Front End.

Successful Sensor Front Ends usually consist of the following key elements in realizing a complete solution

1. Robust architectural definition
2. Sensor interface electronics – often a preamplifier or instrumentation amplifier

ADC

1. Sensor excitation circuits
2. Calibration and Production support

Cosmic Circuits engineers work with customers through this phase to define an optimal solution after weighing feasibility of IC implementation.
