Low-voltage wide gm adjustable range highly linear BiCMOS OTA

A low distortion low-voltage BiCMOS OTA with wide gm adjustment range and constant input range is presented. It is based on a highly linear voltage-to-current converter input stage merged with translinear loops that implement linear electronically programmable current mirrors. Experimental results are provided that confirm the characteristics of the proposed OTA with a single 1.7V supply, 1.2V ...

On the Design of Linearly Tunable Wide Input Voltage Range CMOS OTA and Its Application

In this paper, a CMOS OTA with a wide input voltage range and linearly tunable transconductance gain (gm) is presented. To achieve the linear control of transconductance, the bias current (IB) is squared by using the current squarer circuit before applying it into the main CMOS OTA. In addition, the source degeneration technique is used to extend the input voltage range. The frequency response ...

Highly linear low voltage low power CMOS LNA

A highly linear, low voltage, low power, low noise amplifier (LNA) using a novel nonlinearity cancellation technique is presented in this paper. Parallel Inductor (PI) matching is used to increase LNA gain by 3 dB at the desired frequency. The linear LNA was designed and simulated in a TSMC 0.18μm CMOS process at 5GHz frequency. By employing the proposed technique, the IIP3 is improved by 12 dB...

Novel Low-Voltage Low-Power Full-Swing BiCMOS Circuits

AbstructA novel BiCMOS full-swing circuit technique with superior performance over CMOS down to 1.5 V is proposed. A conventional noncomplementary BiCMOS process is used. The proposed pull-up configuration is based on a capacitively coupled feedback circuit. Several pull-down options were examined and compared, and the results are reported. Several cells were implemented using the novel circuit...
