Abstract
Apparatus and associated methods relate to a pole-zero balanced power switching regulating system for high power and frequency application. In an illustrative example, a trans-inductor voltage regulator (TLVR) may include at least two phases. For example, each phase may include a current inducing circuit. A second-order current sensing circuit (SOCSC) operably coupled to the TLVR may be configured to measure the current flow of each phase. In some implementations, the TLVR may include a first transfer function with two zeros and one pole and the SOCSC may include a second transfer function with two DCR-poles and one DCR-zero. For example, a difference between corresponding poles and zeros of the first and second transfer functions may effectively cancel each other. For example, a gain and phase difference between the first and the second transfer functions are close to zero. Various embodiments may advantageously allow fast transient current measurement at the TLVR.
