Here we discuss an OTA-C topology, suitable for high speed applications. In this topology the tuning circuit is separated from the main amplifier, which enables reduction in the number of stack transistors and hence, makes the circuit suitable for sub-micron technology. While smaller devices provide better speed, their larger channel length modulation makes the phase response more sensitive to the...
In this work, a high gain and high bandwidth rail-to-rail operational amplifier with slew rate boost circuit is presented. The constant gm is enhanced through a source-to-bulk bias control of an input pair. A source degeneration scheme is applied to realize an input common-mode range insensitive output stage. Several compensation schemes are applied to maintain the stability. A slew rate boost circuit...
A 54 MHz-880 MHz low-noise variable-gain amplifier (LNA) for use in cable TV tuners is designed in a 0.18-mum CMOS process. An active shunt feedback is used to achieve wideband input matching without degrading the noise figure. Inductive shunt-peaking is employed at the output to extend bandwidth. The LNA gain can be tuned from 10 dB to 22 dB. The amplifier measures a NF of 2.8dB in the high-gain...
