1. What is a resistor network?
A resistor network is a circuit system composed of multiple resistor elements connected in a certain topological structure. These resistor elements can be discrete resistors or multiple resistors with consistent parameters integrated on a substrate, which are made by comprehensive mask, photolithography and sintering process technologies.
Basic composition and characteristics of resistor networks
Structure: A resistor network can be composed of discrete resistors or multiple resistors with consistent parameters integrated on a substrate. These resistors are connected together through specific process technologies to form a complex circuit structure.
Characteristics: Resistor networks have various characteristics, including but not limited to stability, accuracy and reliability. Integrated resistor networks are often used in application scenarios that require high accuracy and high reliability due to their consistency and stability. -
2. What is an array in a circuit?
Types of arrays
Gate array: The gate array is a motherboard with basic logic gates formed on the silicon wafer provided by semiconductor manufacturers. Users can wire on the motherboard according to their needs to form the required circuit. This chip is semi-customized and is suitable for occasions that require specific functions.
PLA (Programmable Logic Array): PLA is a variant of ROM. Its storage unit body and address decoder are both user-programmable. It is suitable for occasions that require flexible configuration of logic functions.
PAL (Programmable Array Logic): PAL is also a variant of ROM. Its storage unit body is not programmable, but the address decoder is user-programmable. It is suitable for occasions that require partial programmable logic.
GAL (General Array Logic): GAL is more powerful than PLA and PAL, and is suitable for occasions that require more complex logic functions.
PGA (Programmable Gate Array): PGA is an array logic circuit with strong logic functions. Users can interconnect the gate circuits in the gate array as needed to achieve the required logic functions.
PMA (Programmable Macrocell Array): PMA is more powerful than PGA and has a higher degree of integration. It is suitable for occasions that require higher performance and complex logic.
PLD (Programmable Logic Device): PLD is a collective name for array logic circuits other than RAM, and is suitable for occasions that require flexible configuration of logic functions.

3. Does the resistor network have polarity?
Resistor networks do not have polarity. Resistors themselves have no polarity. Whether they are fixed resistors, adjustable resistors or various sensitive resistors, there is no distinction between positive and negative poles. The main difference between resistors lies in the difference in resistance value and packaging, not polarity.
In a resistor network, the way the resistors are connected determines the behavior of the circuit.

4. How to solve a resistor network?
The basic methods for solving resistor networks include using Kirchhoff equations, symmetry simplification, current distribution method, limit method, etc.
Kirchhoff's Equations
Kirchhoff's equations are a general method for solving complex circuits, which include two types of equations:
Node current law: The sum of the outflow currents at any node in the circuit is equal to the sum of the inflow currents.
Loop voltage law: The sum of the voltage drops in any closed loop in the circuit is equal to zero.
Symmetry simplification
Use the symmetry in the network structure to simplify the calculation of equivalent resistance. If there are completely symmetrical points in the circuit, the potentials of these points are equal, and the circuit can be simplified by connecting or disconnecting these points.
Current distribution method
By analyzing the distribution of current in the circuit, the law of current distribution is used to simplify the calculation. For example, after finding the law of current distribution in a complex circuit, the circuit can be simplified by merging or disconnecting certain parts.
Limit method
In some cases, a specific problem is solved by taking the limit. For example, assuming that when a voltage is applied between two points, the voltage drop of some resistors is zero, thereby simplifying the circuit.
