Linear - Analog Multipliers, Dividers

1. Overview

Analog Multipliers and Dividers are linear integrated circuits (ICs) designed to perform mathematical operations on continuous analog signals. These devices multiply or divide two analog input signals to produce an output proportional to their product or quotient. Their ability to handle real-time signal processing tasks makes them critical in applications such as modulation/demodulation, power measurement, and sensor signal conditioning. With advancements in semiconductor technology, these ICs have become essential components in modern communication systems, industrial automation, and precision instrumentation.

2. Major Types and Functional Classification

TypeFunctional FeaturesApplication Examples
Four-Quadrant MultipliersSupport both positive/negative inputs and outputs; high linearityCommunication signal modulation, phase-locked loops
Two-Quadrant MultipliersAccept one bipolar and one unipolar inputPower measurement, amplitude control
DividersPerform analog voltage/current division with stable quotient outputFrequency synthesis, feedback control systems
Programmable Gain Amplifiers (PGA)Digitally adjustable gain control via multipliersData acquisition systems, sensor calibration

3. Structure and Composition

Typical analog multipliers/dividers consist of: - Input differential amplifiers for signal conditioning - Core multiplier cells based on Gilbert cell architecture (using bipolar/CMOS transistors) - Temperature compensation circuits for stability - Output buffers for impedance matching - Packaging options: DIP, SOP, or QFN for PCB integration Advanced devices integrate laser-trimmed resistors for precision and on-chip references for calibration.

4. Key Technical Specifications
