  • Peak detector circuit
    Patent number: 5969545
    Abstract: A peak detector circuit (100) includes an output transconductance amplifier (102), a current rectifier (104) and an averaging circuit (108). The current rectifier includes an amplifier (115) which reduces input impedance of the current rectifier to increase the operating frequency of the peak detector circuit. An isolator (106) employs a current mirror (509) with a cascode transistor (512) having a bias potential which is dynamically adjusted to achieve accurate mirroring. An amplifier of a common mode feedback circuit (110) has improved linearity.
