Abstract
The invention relates to a double integration or dual slope delta-sigma coder. This coder comprises a first adder receiving on an input (36) a signal E(p) to be encoded and on an input (37) the coded signal S(p), a first integrator receiving on an input (32) an output signal of the first adder, a second adder receiving on an input (38) the output signal (31) of the first integrator, an input (39) of the second adder receiving a signal proportional to the coded signal, a second integrator connected to the second adder, a quantizer circuit (43), whereof one input (D) is connected to an output (41) of the second integrator, an output Q of said quantizer circuit supplying the coded signal S(p), wherein the integrators and adders are constituted by circuits comprising operational amplifiers (30, 40) and switched capacitor arrangements (35, 36, 45, 46).
