Abstract:
The invention relates to a circuit for low noise, fully differential amplification. A feedback signal (121) is detected in a differential output step of the differential amplification circuit by means of a voltage distributor formed by a first feedback resistance (119) and a second feedback resistance (120). A first output signal (111) is provided at a first output circuit node (117) and a second output signal (112) is provided at a second output circuit node (118). The respective first and second output signals (111) or (112) form a full output signal which corresponds to an input signal formed by a first and a second input signal (101) or (102). A load current (134), an input current (132) and a reference current (132) are established by means of a load current source (128), an input current source (131) and a reference current source (127). A matching transistor (301) is used to adjust an adaptation between the load current source (128), the input current source (131) and the reference current source (127). A feedback signal (121) of the differential amplification circuit is compared with a reference voltage (122) in a reference step, and the load current (134) is mirrored in the differential input step, in a current mirror device.

The controller can be applied in particular for controlling the synchronous parallel-serial converter for converting a parallel input signal comprising k bit positions into a serial output signal sequence synchronously with the clock signal (clk_hr_i), which converter is provided in a transmitting circuit in the interface circuit of a very fast DDR DRAM semiconductor memory component of the coming memory generation (e.g. DDR4).

Abstract:
The synchronous parallel-series converter has first shift register (SRod) which accepts odd-numbered part (D1od(1/8)) of input signal synchronously to rear and front flank of the clock pulse (clkhri) with a first load signal (odloadi) and lets it serially pass as first one-bit signal sequence (D2od(1/2)). A second shift register (SRev) accepts an even-numbered part (D1ev(1/8)) of input signal synchronously to front or rear flank of the clock pulse with a second load signal (evloadi) and lets it serially pass as a second one-bit signal sequence (D2ev(1/2)). A fusion unit (M) accepts the first one-bit signal sequence from first shift register and second one-bit signal sequence from the second shift register. The clock pulse and the first one-bit signal sequence merges synchronously with the rear or front flank of the clock pulse. The second one-bit signal sequence merges synchronously with the front or rear flank of the clock pulse to output signal (D3(1/1)). An independent claim is also included for the use of the synchronous parallel-series converter.

The device has 2 to the power of b digital to analog converters, where b is an integer greater than 0 and each converter converts a digital value containing a-b bits, where a is the number of bits in the value to be converted. The value fed to the a converter corresponds to the a-b most significant bits of the sum of the value to be converted and to a value given by a stated relationship.
Abstract:
The device has a memory cell operated in a mode, in which the cell is directly operated as a memory device for error-correcting code (ECC)-information. The cell is operated in another mode, in which the cell serves as the memory device for storing information, which is different from the ECC -information. A signal control device (CTRL) is used for signaling in such a manner that the cell is operated in the former or latter mode. An independent claim is also included for a method for operating a semiconductor memory device.
Abstract:
The invention provides an amplifier arrangement which is of multistage design. The output transistor in the output stage has a coupling path between its control input and its controlled path. The coupling path comprises a series circuit comprising a Miller compensation capacitance and a resistance with a controllable resistance value. It is thus possible to ensure stable operation of the amplifier regardless of bias and load conditions while simultaneously reducing the quiescent current drawn.
