A CMOS Inverter-Based Self-biased Fully Differential Amplifier
Abstract : A CMOS self-biased fully differential amplifier is
presented. Due to the self-biasing structure of the amplifier and its
associated negative feedback, the amplifier is compensated to achieve
low sensitivity to process, supply voltage and temperature (PVT)
variations. The output common-mode voltage of the amplifier is adjusted
through the same biasing voltages provided by the common-mode feedback
(CMFB) circuit. The amplifier core is based on a simple structure that
uses two CMOS inverters to amplify the input differential signal.
Despite its simple structure, the proposed amplifier is attractive to a
wide range of applications, specially those requiring low power and
small silicon area. As two examples, a sample-and-hold circuit and a
second order multi-bit sigma-delta modulator either employing the
proposed amplifier are presented. Besides these application examples, a
set of amplifier performance parameters is given.
