High gain two-stage amplifier with positive capacitive feedback compensation

A novel topology for a high gain two-stage amplifier is proposed. The proposed circuit is designed in a way that the non-dominant pole is at output of the first stage. A positive capacitive feedback (PCF) around the second stage introduces a left half plane (LHP) zero which cancels the phase shift introduced by the non-dominant pole, considerably. The dominant pole is at the output node which m...

A High Gain and Low Noise Cmos Gilbert Mixer with Improved Linearity Based on Mgtr and Switched Biasing Technique

This brief presents the design of an improved linear Gilbert mixer with high conversion gain and low noise figure by using multiple gated transistor (MGTR) and switched biasing technique. This mixer operates at a radio frequency (RF) of 2.4GHz with a local oscillator (LO) power of 5dBm in UMC 180nm process. The MGTR method is used to increase the linearity of the proposed mixer by the parallel ...

A low noise amplifier with improved linearity and high gain

In this paper presents a optimization of linearity of low noise amplifier by using post linearization techniques. in this technique we have used diode connected mosfet as IMD sinker also used interstage matching for gain enhancement and reducing the effect of nonlinearity in common gate stage of cascode amplifier, this has done by using UMC .18um CMOS Technology in cadence tool. We got gain 14d...

. Cmos Mixer with Improved Linearity

A new linearization technique for a CMOS high frequency mixer will be presented. The reduction of the total harmonic distortion coefficient is achieved by replacing the simple differential amplifier from the basic multiplier circuit with a cross-connection differential amplifier, with the advantage of canceling the third-order harmonic from the output signal expression. The circuit was implemen...

Low noise, high linearity double-balanced active mixers using lossless feedback

performance while requiring a considerably less LO power than is required of Class III diode ring mixers having comparable performance [6]. However, the topology has provided little improvement in the NF of earlier active mixer topologies. In the lossless feedback active mixer, an input IF (or RF) signal having amplitude A and frequency ω S is applied differentially to the input terminals of a ...
