摘要

本文提出了一种基于ccii的低压可调谐振荡器。该电路使用了新的第一代和第二代电流输送机，设计用于在低至1.5 V的典型电源电压下工作，最低为1.2 V。采用ALCATEL-MIETEC公司的0.5 μm CMOS工艺进行SPICE仿真，验证了理论分析的正确性。特别是考虑了CCI和CCII模型。仿真结果表明，该滤波器具有较大的调谐范围(7 ~ 9.5 MHz)，总谐波失真小于1.5%，在1.5 V电源下功耗为530 μW。

A 1.5 V CCII-based tunable oscillator for portable industrial applications

In this paper a low-voltage CCII-based tunable oscillator is presented. The circuit makes use of new first and second generation current conveyors, designed to operate at typical supply voltages as low as 1.5 V, the minimum being 1.2 V. SPICE simulations, performed by 0.5 μm CMOS process from ALCATEL-MIETEC, well confirm the theoretical analysis. In particular, CCI and CCII models have been taken into account. Simulation results give a large tuning range (7-9.5 MHz), a total harmonic distortion lower than 1.5% and a 530 μW power consumption at 1.5 V supply.
