  We propose an electric circuit array with topologically protected
uni-directional voltage modes at its boundary. Instead of external bias fields
or floquet engineering, we employ negative impedance converters with current
inversion (INICs) to accomplish a non-reciprocal, time-reversal symmetry broken
electronic network we call topolectrical Chern circuit (TCC). The TCC features
an admittance bulk gap fully tunable via the resistors used in the INICs, along
with a chiral voltage boundary mode reminiscent of the Berry flux monopole
present in the admittance band structure. The active circuit elements in the
TCC can be calibrated to compensate for dissipative loss.
