Abstract: An amplifier (1) includes an analogue-to-digital converter (ADC) (7) and a switched capacitor output stage (8). The ADC (7) converts an analogue signal into a digital signal containing a sequence of symbols. The switched capacitor output stage (8) charges and discharges a capacitor to produce charge pulses at an output (3). During discharge, switches selectively couple the capacitor to the output (3) in opposite directions to produce charge pulses of opposing polarity. The values of the symbols in the digital signal are used to decide the polarity of charge pulses. In this manner, amplification can be achieved without introducing a direct current (DC) component to the signal at the output (3).

Abstract: A switched-capacitor amplifier arrangement and a method to amplify a signal are presented. A forward path has at least one switched capacitor (10) controlled by a clock signal, thus providing an amplification phase (1) of the forward path and an additional clock phase (2). According to the proposed principle, a damping means (22) is connected to the forward path, the damping means being designed for attenuation of the signal peak at the beginning (2p) of the amplification phase. This avoids an undesired feed forward effect at the beginning of the amplification phase of an SC circuit.

Abstract: Methods and apparatus for implementing and/or using amplifiers and performing various amplification related operations are described. The methods are well suited for use with, but not limited to, switching type amplifiers. The methods and apparatus described herein allow for the use of switching amplifiers while reducing and/or compensating for distortions that the use of such amplifiers would normally create. The described methods and apparatus can be used alone or in combination with various novel signaling schemes which can make it easier to compensate for the non-ideal behavior of switching amplifiers in such a way as to enable practical application in wireless transmission and/or other applications.
