This paper presents measuring and experimental results of A/D converters with current mode sigma delta modulators. The sigma delta modulator structures are composed of current mode blocks with transconductance amplifiers and their parasitic input capacitances. Sigma delta modulator structures were designed and simulated by using VLSISPICE COMPASS DESIGN program and finally designed by using UNCLE program and then manufactured via Eurochip service center in [formula] ES2 digital process to verify proposed concept. Three different sigma delta structures: first-order, second-order and multistage third-order were measured and results are shown in the paper.
