发明名称 Resistor circuit and oscillation circuit
摘要 A resistor circuit includes first to Mth resistor circuit units. A (2j−1)th resistor circuit unit includes a (2j−1)th first fuse element and a (2j−1)th resistor provided in series between a (2j−1)th node and a 2jth node, and a (2j−1)th second fuse element provided in parallel with the (2j−1)th first fuse element and the (2j−1)th resistor between the (2j−1)th node and the 2jth node. A 2jth resistor circuit unit includes a 2jth first fuse element and a 2jth resistor provided in series between the 2jth node and a (2j+1)th node, and a 2jth second fuse element that is provided in parallel with the 2jth first fuse element and the 2jth resistor between the 2jth node and the (2j+1)th node. The (2j−1)th first fuse element, the (2j−1)th second fuse element, the 2jth first fuse element, and the 2jth second fuse element are disposed in a fuse region. The (2j−1)th resistor is disposed in a first resistor region formed in a first direction with respect to the fuse region. The 2jth resistor is disposed in a second resistor region formed in a third direction with respect to the fuse region, the third direction being a direction opposite to the first direction.
