摘要

在这封信中，我们提出了一种用于硅基液晶（LCoS）应用的高速，低功耗自启动b类驱动放大器。该放大器采用动态可调自举控制电路，与传统电路相比，电压驱动范围增加了一倍，显著提高了系统在高分辨率环境中的灵活性和性能。该设计驱动120-pF电容性负载，转换速率为13.65 V/µs，稳定时间为0.685µs，同时仅消耗来自5 V电源的7µa静态电流。该驱动器采用0.18 μ m高压互补金属氧化物半导体（HV CMOS）工艺制造，可为多个像素柱供电。测量结果证实了该电路在支持LCoS技术的全息投影和显示方面的有效性。

High-Speed, Low-Power Bootstrapped Class-B Driver Amplifier for LCoS Applications

In this letter, we present a high-speed, low-power bootstrapped class-B driver amplifier for liquid crystal on silicon (LCoS) applications. The amplifier, incorporating a dynamically adjustable bootstrapping control circuit, doubles the voltage driving range compared to traditional circuits, significantly enhancing system flexibility and performance in high-resolution environments. The design drives a 120-pF capacitive load with a slew rate of 13.65 V/µs and a settling time of 0.685 µs, while consuming only 7-µA quiescent current from a 5-V supply. Fabricated using a 0.18 µm high-voltage complementary metal-oxide-semiconductor (HV CMOS) process, the driver can power multiple pixel columns. Measurement results confirm the circuit's effectiveness in supporting holographic projection and display for LCoS technologies.
