<p>1-Bit sigma-delta modulator comprising a loop filter (5,6,8), a first negative feedback loop (13,7,8) and a second negative feedback loop (14,4,5,6,8). The filter sections 5 and 8 are passive filter elements and filter section 6 is a high-gain active filter element. A circuit of this type makes a very high clock rate possible in the decision switch 10. <IMAGE></p> |
