摘要： A multi-channel biopotential signal acquisition system is disclosed. In the system, a plurality of biopotential channels is corrected for common-mode interference. In one aspect, each biopotential channel includes an electrode for providing a biopotential input signal and an associated amplifier for amplifying the biopotential input signal and providing a biopotential output signal. The output signal is processed in a processor. Each biopotential output signal is passed to a common-mode feedback system, which determines an average common-mode signal and feeds that signal back to each of the amplifiers in each of the biopotential channels to enhance common-mode rejection ratio of the system.

摘要： A circuit for digitizing a sum of a first input signal and a plurality of second input signals has a passive adder that sums the second input signals and outputs a summation signal and a multi-bit quantizer circuit. The quanitzer circuit compares the summation signal at a first comparator input with a signal at a second comparator input, which is derived from the first input signal and has an appropriate polarity so that the difference between the summation signal and the signal at the second comparator input is indicative of the sum of the first input signal and the plurality of second input signals. The comparator also produces a comparator output signal based on the sum of the first input signal and the plurality of second input signals. The quantizer circuit also has a control logic block for determining a multi-bit representation of the sum from the comparator output signal.

摘要： A circuit for optoelectronic down-conversion of a terahertz, THz, signal comprises a first photodiode and a second photodiode configured to be excited by an optical beat signal. The photodiodes are coupled in series through a common antenna. The terminals of the antenna are coupled to form an output terminal and the antenna is configured to receive the terahertz, THz, signal. The photodiodes thereby, via the optical beat signal, respectively, down-convert the THz signal and generate a current comprising an intermediate frequency, IF, component and a direct current, DC, component. The respective generated currents are summed at the output terminal, thereby obtaining the IF components and cancelling the DC components.
