Filed: 2001-06-01
Abstract: PURPOSE: A general 4-quadrant analogue-digital multiply is provided to process a negative number and a positive number in an analogue and a digital and output a size as an analogue and a code as a digital after outputting an analogue output as a 4-quadrant multiplication or performing an analogue-digital multiplication. CONSTITUTION: A binary weighted electric current mirror unit(15) mirrors an input current(Iin) by selecting a switching element of a binary weighted current mirror by a digital input. When digital data have a negative value by receiving an output of the unit(15), an electric current conversion unit(11) reverses a current and outputs the current. In the case that digital data are a 2's complement format, a complement conversion unit(17) takes a complement of an input of a digital data size unit and selects a corresponding switching element of the unit(15). In the case that digital data are 2's complement and a code bit(ds) of the digital data is '1', an electric current mirror unit(13) is switched and mirrors a current corresponded to an LSB and adds the current to an output. An input current code detecting unit(19) detects a code of an input current. A multiplexer selects a signal for controlling the electric current conversion unit(11), outputs an analogue output as a 4-quadrant multiplication, or outputs only size value as an analogue after a multiplication.
