Circuit configuration for controlling the transmitting power of a battery-operated transceiver

A circuit configuration is provided for controlling the transmitting power of a battery-operated transceiver. A high transmitting power of a mobile transceiver generates a high voltage drop across an internal impedance of the battery which can lead to the device switching off. A reduction in the transmitting power in dependence on the battery voltage is therefore proposed. The battery voltage is thus compared with a reference voltage and a signal representing a nominal transmitting power is correspondingly corrected. The circuit can be integrated in a simple manner with analog components in an IC.

The present invention is directed to a design of and a method to synthesize polycations for gene (DNA and RNA) delivery. According to this design, the polycations (also said cationic polymers) are formed by polymerization of endogenous monomers bearing sufficient amino groups through degradable bonds with linker molecules or with themselves. The amino group-bearing monomers are those naturally existing in or nontoxic to human body. The linker molecules are those which are not only degradable to nontoxic fragments but also able to release the amino group-bearing monomers in their native state upon degradation. Some examples for the endogenous amino group-bearing monomers are spermine, spermidine, serine or N,N-dimethyl serine, and histidine. Examples for the degradable chemical bonds formed between the amino group-bearing monomers are carbamate, imine, amide, carbonate, and ester. In order to improve degradability or proton sponging effect, low pKa (<8) amino group(s) or other electron donating group(s) is incorporated in the linker between the two (or three) reactive groups for linking the amino group-bearing monomers. These polycationic carrier systems can be used for nano-encapsulation and transfection of gene materials.
