Abstract: An electronic circuit, including a signal transmitter, a signal generator and a ring oscillator, has a topography that is entirely symmetrical so that signals transmitted or produced by the circuit have symmetrical output signals tolerant to input timing skew, output delay/slewrate-mismatch, and complementary device-mismatch. Each P-type transistor in the circuit has a correspondingly connected P-type transistor connected to signal nodes and supply voltage nodes in a complementary manner. Similarly, each N-type transistor in the circuit has a correspondingly connected N-type transistor connected to signal nodes and supply voltage nodes in a complementary manner.
