This paper presents an approach to [sigma delta] modulators relying on current mode sampled data circuits with switched transconductances. The [sigma delta] modulator structures are composed of current mode building blocks with transconductance amplifiers and capacitors. All building blocks and three different [sigma delta] structures: first-order, second-order and third-order two-stage are designed and simulated by using VLSISPICE COMPASS DESIGN programs on SUNSPARC20 computer and then manufactured via Eurochip service center in 0.7 [mu]m ES2 digital process to verify proposed concept.
