Claim Text:
1. A system for extending the frequency response of an accelerometer while reducing noise produced by the accelerometer, comprising a compensation circuit including a first T-network in parallel with a first capacitor, said first T-network defined by two common-value resistors and a capacitor connected therebetween and to ground, an operational amplifier having a non-inverting input coupled to ground, an inverting input, and an output, and a second T-network in parallel with a parallel resistance-capacitance (RC) circuit, wherein said second T-network is identical to said first T-network, and wherein said parallel RC circuit is defined by a second capacitor in parallel with a first resistor, wherein said first T-network is connected between the accelerometer's output and said inverting input of said operational amplifier, and wherein said second T-network in parallel with said parallel RC circuit is connected to said inverting input of said operational amplifier and said output of said operational amplifier.
