This paper presents a new approach to A/D converters with [sigma delta] modulations using switched transconductance amplifiers. The layout of the [sigma delta] structures with current mode blocks, transconductance amplifiers and input capacitors are designed using COMPASS DESIGN AUTOMATION Development Tools in 0.8 MICRON technology. The extraction of the modulator was made from this layout and the net list of the modulator was created for the SPICE simulator. Three different [sigma delta] structures: first-order, second-order and multistage are simulated by using COMPASS VLSISPICE program on SUNSPARC20 computer to verify proposed concept.
