چکیده
This Paper presents the design of a wideband variable gain amplifier (VGA) using 0.18 μm standard CMOS technology. The proposed VGA realizes wideband flat gain using wideband flat negative capacitance. It achieves a 3 dB gain bandwidth of 1 GHz with a maximum gain of 23 dB. Also, it shows P1 dB of −33 to −6 dBm over the gain range of −28 to 23 dB. The overall current consumption is 5.5 mA under a 1.5 V supply. key words: variable gain amplifier, wideband, cascode, negative capacitance

A Variable Gain Amplifier for Wideband DCRs using 0.13μm CMOS Technology
A wideband variable gain amplifier (VGA) design is introduced with two different schemes. It is based on a fully differential amplifier with resistive loads, and a Negative Miller Capacitance technique is used to increase the bandwidth of the amplifier. The amplifier consists of three stages, and the gain is varied through the second and third stages, where they are degenerated by a voltage con...
متن کاملA New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
