摘要

本文提出了一种新型的可变增益放大器(VGA)和一种新型的压控环振荡器(VCRO)。提出的两种方案依赖于具有单个附加器件的相同控制逆变器单元。推导了VGA的电压增益与控制电压的关系，以及VCRO的振荡频率与控制电压的关系。最后，采用45 nm CMOS技术，在电源电压VDD为1 V的情况下，对所提出的VGA和VCRO进行了仿真。

Novel CMOS-Inverter Based VGA and VCRO

In this paper, a novel variable-gain amplifier (VGA) and a novel voltage-controlled ring oscillator (VCRO) are proposed. The two proposed schemes depend on the same controlled inverter unit with a single added device. The relationship between the voltage gain of the proposed VGA and the control voltage and the relationship between the oscillation frequency of the proposed VCRO and the control voltage are both derived. Finally, the proposed VGA and VCRO are simulated adopting the 45 nm CMOS technology with a power-supply voltage, VDD, equal to 1 V.
