This programmable gain amplifier (PGA), designed for sensor applications, enhances analog front end (AFE) performance by adjusting the amplification of input signals for optimal sensor data acquisition. A crucial component for achieving high dynamic range in sensor applications, it supports efficient signal conditioning.\n\nThe PGA ensures that weak signals from sensors are appropriately amplified before conversion, enabling an improved signal-to-noise ratio, paramount in precise sensing operations—from simple ambient measurements to complex industrial processes.\n\nLeveraging SMIC's 180nm fabrication process, the PGA exhibits low noise and high tolerance, providing stable amplification under varying environmental conditions, thus recommended for robust industrial sensor applications and precision measurement setups.
