温度计-二进制（TM2B）编码器是闪存模数转换器（ADC）的重要组成部分。在本文中，我们提出了一种将气泡误差降低到三阶的新方法。而现有的方法只能处理一阶/二阶气泡误差，而不能处理高阶气泡误差。仿真结果表明，该电路所需晶体管数量少，功耗低，优于现有模型。利用Xilinx软件（Verilog代码）对气泡纠错电路进行了仿真，并对仿真结果进行了理论验证。
Thermometer-to-binary (TM2B) encoder is a vital component of a flash Analog-to-Digital Converter (ADC). In this paper, we propose a new approach to subside Bubble Errors up to third-order. Whereas existing approaches deal with first/second-order bubble errors only, and failed with higher order of bubble errors. The simulation results illustrate that the proposed circuit requires lesser number of transistors and consequently consumes less power, which makes the circuit superior to the existing models. Bubble error correction circuit is simulated by using Xilinx (Verilog code) and verified all results with theory.
