Description
Summary:This paper presents a novel peak detect and hold (PDH) circuit for the measurement of the peak voltage of electromagnetic-field probes. These probes are used to capture the fields generated by electrostatic discharge (ESD) events in non-grounded portable devices. Therefore, a circuit combining small size, low power consumption and nano-second operation is needed. A topology using a discrete bipolar transistor structure with OTA and common-base storage capacitor charge control optimally meets the requirements. The circuit performance is demonstrated for different bias point settings. The error between the captured value and the actual pulse peak value is shown as a function of rise time, pulse length, amplitude and bias settings. A comparison with literature, shows unmatched performance with respect to speed and power consumption. Using the bias settings the PDH circuit can be adjusted to the sensor's frequency response to minimize power consumption in a multi-channel system containing sensors of different bandwidth.
