Improvements in or relating to full-wave rectifiers |
摘要 |
<p>ABSTRACTA full-wave rectifier circuit (70) includes a first transistor (N1) and a second transistor (N2) in combination to form a first transistor pair (N1 and N2) for minimizing the voltage drop between ground (88) and the transponder substrates. A third transistor (P1) and a fourth transistor (P2) operate in combination to form a second transistor pair (P1 and P2) for minimizing the voltage drop between the alternating current peak voltage (118 and 120) and the output voltage (VDD) of the full-wave rectifier (70). The first transistor pair (N1 and N2) and second transistor pair (P1 and P2) are controlled by alternating current voltage input signals (118 and 120). A series regulator circuit (70) decouples the first transistor pair (N1 and N2) and the second transistor pair (P1 and P2) from capacitive loads (C1 and C2) of the full-duplex transponder circuitry (14). <IMAGE></p> |
