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.

Abstract: A process for constructing a micro-electro-mechanical system (MEMS) device includes etching the topside of a silicon wafer to form a first support layer having asymmetric pads. The backside of the silicon wafer is etched to form a top layer with a mirror, beam structures extending from the mirror, and rotating comb teeth extending from the beam structures. Before or after the backside of the silicon wafer is etched, the topside of the silicon wafer is bonded to a glass wafer that forms a second support layer. Prior to bonding the silicon wafer to the glass wafer, the glass wafer may be etched to form a recess and/or a cavity that accommodates mobile elements in the silicon wafer. Due to the asymmetry of the pads in the first support layer below the rotating comb teeth in the top layer, oscillation can be initiated.
