ABSTRACT:
A data weighted average (DWA) structure including a first delay unit, a binary to thermometer code converter, an adder, a second delay unit, a decoder, a barrel shifter, and a plurality of signal lines is provided. The first delay unit delays an input digital signal. The binary to thermometer code converter converts an output signal of the first delay unit into a thermal code. The second delay unit delays an output signal of the adder. The adder adds the input digital signal to an output signal of the second delay unit. The decoder decodes the output signal of the second delay unit. The barrel shifter generates an output signal from the thermal code in accordance with an output signal of the decoder. The signal lines route the output signal of the barrel shifter into two independent control signal groups.
